The four ADC and two DAC channels each have an SNR of at least 96 dB and a THD + N of at least -88 dB. The two serial audio ports are compatible with I2S, left justified, right justified, and TDM modes, with tristating for interfacing to digital audio data. The operating voltage is 1.8 V, with an on-board regulator generating the digital supply voltage. If desired, the regulator can be powered down, and the voltage can be supplied externally. The input signal path includes flexible configurations that can accept single-ended analog microphone inputs as well as up to eight digital microphone inputs. Two microphone bias pins provide seamless interfacing to electret microphones. Each input signal has its own PGA for volume adjustment. The ADCs and DACs are high quality, 24-bit - converters that operate at a selectable 12 kHz to 768 kHz sampling rate. The ADCs and DACs have an optional high-pass filter with a cutoff frequency of 1 Hz and fine-step digital soft volume controls. The stereo DAC output is capable of differentially driving a headphone earpiece speaker with 16 impedance or higher. There is also the option to change to line output mode when the output is lightly loaded. The SigmaDSP core is optimized for low power audio processing. This core can be graphically programmed using the SigmaStudio(R) software from Analog Devices, Inc. This software includes a library of audio processing blocks such as filters, dynamics processors, mixers, and low level DSP functions for fast, graphical development of custom signal flows. The FastDSP core has a reduced instruction set that optimizes this codec for noise cancellation. The program random access memory (RAM) and parameter RAM can be loaded with a custom audio processing signal flow built using SigmaStudio. The values stored in the parameter RAM control individual signal processing blocks. The ADAU1787 also has a self-boot function that can load the program and parameter RAMs of both cores along with the register settings on power-up using an external electronically erasable programmable read-only memory (EEPROM). Use the SigmaStudio software to program and control the cores through the control port. Along with designing and tuning a signal flow, the tools can configure all of the ADAU1787 registers. The SigmaStudio graphical user interface (GUI) allows anyone with digital or analog audio processing knowledge to design the DSP signal flow and export the flow to a target application. The interface also provides enough flexibility and programmability for an experienced DSP programmer to have control of the design. In SigmaStudio, the user can connect graphical blocks (such as biquad filters, volume controls, and arithmetic operations), compile the design, and load the program and parameter files into the ADAU1787 memory through the control port. SigmaStudio also allows the user to download the design to an external EEPROM for self boot operation. The ADAU1787 can generate the internal clocks from a wide range of input clocks by using the on-board bypassable fractional PLL. The PLL accepts inputs from 30 kHz to 27 MHz. For standalone operation, the clock can be generated using the on-board crystal oscillator. The ADAU1787 is provided in a small, 42-ball, 2.695 mm x 2.320 mm WLCSP. Rev. A | Page 28 of 280 Data Sheet ADAU1787 SYSTEM CLOCKING AND POWER-UP POWER-DOWN OPERATION AND OPTIONS When pulled low, the PD pin puts the chip in the lowest power state, hardware full chip power-down. If the regulator is used, it also powers down during this state. The chip fully resets in this state and retains no state memory. No communication with the device is possible when the PD pin is low. By default, out of reset, the chip is in the lowest power state that can be entered via a control interface, software full chip powerdown. To enter or exit this power state, use the POWER_EN bit, Bit 0 of Register 0xC00D. When POWER_EN = 0, the I2C/SPI control ports are operational, and everything else is powered down except for the regulator and the crystal, if used. To achieve the lowest power state, set the XTAL_EN bit (Bit 1 of Register 0xC005) = 0. The digital portion of the chip has several power domains. By default, only the domain that powers the control ports and their associated registers are powered on, and the rest of the digital design has its power supplies gated, and its state is lost. There are two options to retain additional state memory during a software full chip power-down. The KEEP_SDSP and KEEP_ FDSP bits, Bit 1 and Bit 0 of Register 0xC00C, respectively, can retain the state of the SigmaDSP program and parameter memories and/or the FastDSP program and parameter memories. The control register map always retains its state when POWER_EN = 0. When POWER_EN = 0, the CM pin or the common-mode output can either maintain its state or not by using the CM_KEEP_ALIVE bit, Bit 4 of Register 0xC00C. When CM_KEEP_ALIVE = 0, the CM voltage is lost when POWER_EN = 0, thus producing the lowest possible software power-down current. However, with CM_KEEP_ALIVE = 0, the ADAU1787 has a longer turn on time because the PLL and other analog blocks rely on the CM voltage. A wait time of 35 ms is needed for CM to charge before any analog blocks, such as the PLL, can be enabled. Conversely, with CM_KEEP_ALIVE = 1, the power-down current is higher, but the start-up time is faster because the 35 ms wait time can be omitted. If CM_KEEP_ALIVE = 1, use the CM_STARTUP_OVER bit, Bit 2 of Register 0xC00D, to fast charge the CM voltage and to have the lowest turn on time by setting CM_STARUP_OVER = 0 before POWER_EN is set to 1. Then, after the 35 ms wait time, set CM_STARUP_OVER = 1 to keep power consumption low. The reset state of CM_STARTUP_OVER is 0. Therefore, if the PD pin is used to power down the device, the step of setting CM_STARTUP_OVER to 0 can be omitted. When POWER_EN = 1, the power supplies on the rest of the digital portion of the chip are enabled. Therefore, this register must be set first during the power-up sequence. The PLL and crystal must be configured and enabled after CM_STARTUP_OVER sequencing is complete. After all the internal digital power supplies are powered up, the PLL is locked, and other needed sequencing is complete, the POWER_UP_ COMPLETE bit (Bit 7, Register 0xC0AB) or an interrupt request (IRQ) indicates such. The IRQ1_POWER_ UP_COMPLETE is Bit 4 of Register 0xC0B1. The IRQ2_ POWER_UP_COMPLETE is Bit 4 of Register 0xC0B4. If the IRQs are used to request an interrupt after POWER_UP_ COMPLETE, the IRQs must be unmasked. The IRQ1_POWER_ UP_COMPLETE_MASK bit (Bit 4, Register 0xC0A4) must be cleared. Similarly, the IRQ2_POWER_UP_COMPLETE (Bit 4, Register 0xC0A7) must be cleared. By default, the IRQs for POWER_UP_COMPLETE are masked. After POWER_UP_COMPLETE = 1, the DSP memories can be programmed. The ADAU1787 has highly flexible block level power controls. Each individual channel of each block can be powered on or off separately. There is a control bit, MASTER_BLOCK_EN, that by default is 0 and that overrides all block level enables except for PLL_EN, XTAL_EN, SDSP_EN, and FDSP_EN. The PLL, SigmaDSP, and FastDSP can be enabled, even when MASTER_ BLOCK_EN = 0. All other blocks are always in power-down in this state, allowing the PLL to be enabled and locked and the DSP memories to be initialized before all other signal path blocks are enabled. When configuring the devices, it is recommended to fully set up all control registers and block level power controls to their desired state, to allow the PLL to lock, to initialize the DSP memories to be used, and then to enable the blocks by setting MASTER_BLOCK_EN = 1. Block level power controls and other settings can be changed on-the-fly while the chip is active. However, care must be taken when enabling or disabling blocks other than the DAC and/or headphone mode blocks that are actively routed out to the DAC and/or headphone mode as audible artifacts may occur. Rev. A | Page 29 of 280 ADAU1787 Data Sheet To power down the chip, set MASTER_BLOCK_EN and POWER_EN low. The device then powers down all blocks and performs any required power-down sequencing. An overview of the power-up sequencing follows: 1. 2. 3. 4. 5. 6. 7. 8. 9. 10. 11. 12. 13. 14. Set PD = 1 if using PD to turn on the low dropout (LDO) regulator, if in use. Wait 20 ms if REG_EN = 1. If CM_KEEP_ALIVE = 0 and REG_EN = 0, ensure that CM_STARTUP_OVER = 0. Set POWER_EN = 1 to ungate all power domains on the digital side. If CM_KEEP_ALIVE = 0 and REG_EN = 0, ensure that CM_STARTUP_OVER = 0. If CM_KEEP_ALIVE = 0 and REG_EN = 0, wait 35 ms. Set CM_STARTUP_OVER = 1. Set XTAL_EN = 1 if the crystal is being used. Configure the PLL using CLK_CTRLx registers and set the XTAL_EN and PLL_EN bits if in use. Configure all other setup bits while the PLL is locking (or at any other time after PD = 1). Ensure that all digital power domains are finished powering up, the PLL is locked, and the sequencing is complete by reading the PLL_LOCK bit in Register 0xC0AB. Verify POWER_UP_COMPLETE bit =1. If this bit is set to 1, proceed further or wait until this bit is set to 1. Ensure that SDSP_EN and FDSP_EN = 1 and initialize the static RAMs (SRAMs). Set MASTER_BLOCK_EN = 1 to power up all the blocks that are enabled. Set FDSP_RUN and SDSP_RUN to 1 for the DSPs to operate. EXAMPLE ADC TO DAC POWER-UP To illustrate the power-on sequencing, an example sequence of register writes (and associated wait times) follows that provides the fastest possible passthrough from ADC0 to DAC0 of the ADAU1787. This sequence assumes a default MCLK input of 24.576 MHz. Apply AVDD and IOVDD. Apply DVDD if REG_EN = 0. If REG_EN = 1, wait 20 ms for DVDD to settle. Set POWER_EN = 1 by writing 0x11 to Register 0xC00D. Wait 35 ms for the CM voltage to power up and stabilize. While waiting, configure the following registers: Enable ADC0 and DAC0 by writing 0x11 to Register 0xC004. Set DAC0 routing to ADC0 by writing 0x44 to Register 0xC03E. Unmute DAC0 by writing 0x84 to Register 0xC03B. After 35 ms have elapsed, set CM_STARTUP_OVER = 1 by writing 0x15 to Register 0xC00D. Write 0x01 to Register 0xC005 to enable the PLL. Set MASTER_BLOCK_EN = 1 by writing 0x17 to Register 0xC00D. The total time from power-up to the ADC0 signal being present on DAC0 is ~80 ms. DVDD LDO REGULATOR There is an LDO voltage regulator that can optionally generate the DVDD supply from the HPVDD supply. If the REG_EN pin is tied to ground, this regulator disables, and an appropriate DVDD voltage must be supplied externally on the DVDD pin. If the REG_EN pin is tied to AVDD, the LDO regulator enables and generates the required DVDD voltage. The DLDO_CTRL bit determines the voltage of the LDO output. By default, the output is set to 0.9 V. The LDO requires the CM voltage to operate. Therefore, even if CM_KEEP_ALIVE = 1, the CM output remains present if POWER_EN = 0. Therefore, to achieve the lowest possible power-down power when REG_EN = 1, set the PD low. CLOCK INITIALIZATION The ADAU1787 can generate its clocks either from an externally provided clock on the BCLK_0, BCLK_1, FSYNC_0, FSYNC_1, or MCLKIN pin or from a crystal oscillator. In both cases, the on-board PLL can be used or the clock can be fed directly to the core. When a crystal oscillator is used, the crystal oscillator function must be enabled in the XTAL_EN and XTAL_MODE bits. If the PLL is used, it must always be set to output 49.152 MHz. The PLL can be bypassed if a clock of 24.576 MHz is available in the system, which can be accomplished by setting PLL_BYPASS = 1. Bypassing the PLL saves system power but limits the processing available in the SigmaDSP to the lower clock rate. PLL Enabled Setup To program the PLL during initialization or reconfiguration of the codec, take the following steps: 1. 2. 3. 4. 5. Ensure that POWER_EN = 1. Ensure that PLL_EN = 0. Set the PLL control registers (Register 0xC00E through Register 0xC015). Write 1 to PLL_UPDATE in Register 0xC016 to propagate the PLL settings. Enable the PLL using the PLL_EN bit. Other blocks can be powered up while the PLL is not enabled or locked. However, if the PLL is enabled and not locked, all other circuitry waits until the PLL is locked to begin the power-up sequences. Rev. A | Page 30 of 280 Data Sheet ADAU1787 Control Port Access During Initialization Input Clock Divider Any control registers can be accessed at any time during initialization, before PLL is enabled, or during PLL lock. To access SigmaDSP memories, SDSP_EN must be set to 1, and the PLL must be locked, if in use. To access FastDSP memories, FDSP_EN must be set to 1, and the PLL must be locked, if in use. Before reaching the PLL, the input clock signal goes through an integer clock divider to ensure that the clock frequency is within a suitable range for the PLL. The PLL_INPUT_PRESCALER bits set the PLL input clock divide ratio. The input frequency limits of the PLL are specified after this input prescale divider. Therefore, the frequency after division must fall within specified range. PLL The PLL can use any of the BCLK_x, FSYNC_x, or MCLKIN signals as a reference to generate the core clock, and the source is selected via the PLL_SOURCE bits. Depending on the input clock frequency, the PLL must be set for either integer or fractional mode. The PLL can accept input frequencies in the range of 30 kHz to 27 MHz. The PLL output frequency can be set to be between 32 MHz and 50 MHz. All internal sampling rates specified within the data sheet assume a PLL output frequency of 49.152 MHz, which is a 1024 x 48 kHz sample rate. If the PLL output is set at a different frequency, all internal sampling rates adjust accordingly. For example, if the PLL output is set at 32.768 MHz, which is 1024 x 32 kHz, all internal sampling rates must be adjusted by 32 kHz / 48 kHz or 0.667 ratio. Integer Mode Integer mode is used when the PLL output is an integer multiple of the PLL input clock. For example, if the PLL input clock = 12.288 MHz and the PLL_INPUT_PRESCALER + 1 = 1, the PLL required output = 49.152 MHz. Therefore, R = 49.152 MHz/12.288 MHz = 4, where R is PLL_INTEGER_DIVIDER. Another example is as follows, if PLL input clock = 48 kHz, the PLL required output = 49.152 MHz, then R = 49.152 MHz/ 48 kHz = 1024. In integer mode, the values set for N and M are ignored. Figure 52 lists common integer PLL parameter settings for 48 kHz sampling rates. The chip can function with the PLL disabled if the PLL is bypassed by setting the PLL_BYPASS bit to 1 and providing a fixed 24.576 MHz clock to the core via the PLL_SOURCE bits and appropriate MCLKIN/BCLK_x pin. All blocks operate the same in PLL bypass mode except the SigmaDSP, which runs at half speed relative to the PLL being on and, therefore, can only execute half as many instructions.

A clock output of varying divisions of the PLL output can be generated on any of the MPx pins. For example, if MCLKIN = 13 MHz and fS = 48 kHz, the PLL required output = 49.152 MHz and POWER SUPPLY SEQUENCING (R + (N/M)) = 49.152 MHz/13 MHz = (3 + (1269/1625)) where: R = 3. N = 1269. M = 1625. AVDD, HPVDD, and IOVDD are nominally 1.8 V, and DVDD is set at 0.9 V when using the on-board regulator. On power-up, AVDD and HPVDD must be powered up before or at the same time as IOVDD. Do not power up IOVDD when power is not applied to AVDD. Table 14 lists common fractional PLL parameter settings for 48 kHz sampling rates. When the PLL is used in fractional mode, it is important that the N/M fraction be kept within the 0.1 N/M 0.9 range to ensure correct operation of the PLL. When used in fractional mode, the input to the PLL after the input divider must be 1 MHz. MULTICHIP PHASE SYNCHRONIZATION Multiple ADAU1787 devices can be ensured to remain in phase synchronization across the respective audio channels of the devices by setting the SYNC_SOURCE bit settings to use the same signal that both chips share. SYNC_SOURCE can be set to derive the phase synchronization signal from FSYNC_x. If only the shared serial ports between the two ICs are asynchronous to the core clock, then the SYNC_SOURCE must use the input asynchronous sample rate converter (ASRC). Alternatively, if no serial port is used, an internal synchronization source can be used. Enabling the PD pin powers down all analog and digital circuits and resets the devices to its default state. Before enabling PD (that is, setting it low), mute the outputs to avoid any pops when the IC is powered down. PD can be tied directly to IOVDD for normal operation. Power-Down Considerations When powering down the ADAU1787, mute or power down the outputs before the power supplies are removed. Otherwise, pops or clicks may be heard. Table 14.

Each of the four analog input channels can be configured in singleended mode or single-ended with PGA mode. There are also inputs for up to eight digital microphones. The analog inputs are biased at the CM voltage. Connect unused input pins to the CM pin or ac-couple the pins to ground. Figure 55 shows the phase variation between various blocks within the ADAU1787. The gray waveform shows the signal path from analog in to digital output or analog output, and the black waveform shows the signal path from digital in to analog output. With no PGA or line input mode, the input impedance is fixed at 14.3 k. Analog Microphone Inputs For microphone signals, the ADAU1787 analog inputs can be configured in single-ended with PGA mode. The PGA settings are controlled in Register 0xC021 through Register 0xC029. The PGA is enabled by setting the PGAx_EN bits. ADAU1787 PGA AINx There is phase inversion from the analog input and the ADC, and similarly, from the DAC and headphone outputs (see Table 15). However, there is no phase inversion in the digital blocks. MICROPHONE 0dB TO +35.25dB 2k MICBIASx Input Impedance The input impedance of the analog inputs varies with the gain of the PGA. This impedance ranges from 0.97 k at the 35.25 dB gain setting to 20.26 k at the 0 dB gain setting. The resistors inside the ADAU1787 are precisely matched to each other, resulting in very little gain error. However, the exact value of the resistors depends on various conditions in the silicon manufacturing process and can vary by as much as 20%. 20127-157 Phase Difference Various Signal Path ADAU1787 The optional 10 dB PGA boost, set in the PGAx_BOOST bits, does not affect the input impedance. This setting is an alternative way of increasing gain without decreasing input impedance. Figure 54.

A | Page 34 of 280 Data Sheet ADAU1787 Analog Line Inputs PGAs Line level signals can be input on the AINx pins of the analog inputs. Figure 56 shows a single-ended line input using the AINx pins. When using single-ended line input, the PGA must be disabled using the PGAx_EN bits. The PGAs have a programmable gain from 0 dB to 35.25 dB. The gain is controlled via the PGAx_GAIN registers. The gain can be increased by 10 dB by setting the PGAx_BOOST register to 1. LINE INPUT 0 AIN0 LINE INPUT 1 AIN1 LINE INPUT 2 AIN2 LINE INPUT 3 AIN3 20127-158 ADAU1787 The slew between gain steps is performed automatically when the PGAx_SLEW_DIS register is 0. When the PGAx_SLEW_DIS register is set to 1, the slew can be performed manually with the 5 LSBs of the PGAx_GAIN register. These bits are intended only for controlling smoother transitions between the 0.75 dB steps of the 6 MSBs (PGAx_GAIN[10:5]) and must only be set to a 0 when not transitioning the gain. DIGITAL MICROPHONE INPUTS Figure 56. Single-Ended Line Inputs Precharging Input Capacitors Precharge amplifiers are enabled by default to quickly charge large series capacitors on the analog inputs. Precharging these capacitors prevents pops in the audio signal. The precharge circuits are powered up by default when an ADC channel is enabled and remain on for an amount of time determined by the ADC_AIN_CHRG_TIME bits register control. The internal impedance for the AINx pins is 750 in this mode. However, at startup, the internal impedance is governed by the time constant of the reference voltage at the CM pin because the input precharge amplifiers use the CM voltage as a reference. Microphone Bias The ADAU1787 includes two microphone bias outputs: MICBIAS0 and MICBIAS1. These pins provide a voltage reference for electret analog microphones. The MICBIASx pins can also cleanly supply voltage to digital or analog MEMS microphones with separate power supply pins. The MICBIASx voltage is set in the microphone bias control register (MBIAS_ CTRL). Using this register, either the MICBIAS0 or MICBIAS1 output can be enabled and disabled. The gain options provide two possible voltages: 0.65 x AVDD or 0.9 x AVDD. Many applications require enabling only one of the two bias outputs. Enable the two bias outputs when multiple microphones are used in the system or when the positioning of the microphones on the PCB does not allow one pin to bias all microphones. When using a digital microphone connected to the DMIC01 and DMIC23 pins or the DMIC4_5 or DMIC6_7 flexible multipurpose inputs, the corresponding DMICx_EN registers must be set to enable the digital microphone signal paths. The digital microphone channels can be swapped (left/right swap) by writing to the DMICxx_EDGE bits. The digital microphone inputs are clocked from the DMIC_CLK0 or DMIC_CLK1 pins. The digital microphone data stream must be clocked by these pins and not by a clock from another source, such as another audio IC. The frequency of each DMIC_ CLK output can be set individually via the DMIC_CLKx_RATE bits. Each digital microphone data input pin must be mapped to the corresponding DMIC_CLKx via the DMICxx_MAP registers. Each digital microphone input pair has separate sample rate controls that determine the downsampling ratio. These controls are set via the DMICxx_FS bits. The output sample rate can be set between 12 kHz and 768 kHz. The initial decimation filter order can be selected between fourth- or fifth-order via the DMICxx_DEC_ORDER bits. The fourth-order selection yields the lowest propagation delay, and the fifth-order selection may be needed to maintain full performance with some high dynamic range microphones. The DMICxx_FCOMP bits control whether or not the high frequency roll-off of the decimation filter is compensated for. No compensation gives the lowest propagation delay but slight attenuation in the pass-band. There are separate digital volume controls and 1 Hz high-pass filters for each digital microphone channel. The input pulse density modulation (PDM) is mapped directly to the relative pulse code modulation (PCM) full-scale. For example, a 50% PDM density input generates a -6 dBFS output with a volume control setting of 0 dB. The digital microphone signals and the ADCs are completely independent and do not share decimation filters. Rev. A | Page 35 of 280 ADAU1787 Data Sheet Digital Microphone Volume Control ADCs The volume setting of each digital microphone channel can be digitally attenuated in the DMIC_VOLx registers. The volume can be set between +24 dB and -71.25 dB in 0.375 dB steps. The digital microphone volume can also be digitally muted in the DMICx_MUTE bits. By default the volume control performs a soft ramp when changed, which can be bypassed for instantaneous change of volume via the DMIC_HARD_VOL bit. The volume control for every channel can be set to use the Channel 0 volume via the DMIC_VOL_LINK bit. When a digital microphone channel is enabled, it starts immediately at the volume level set by its DMIC_VOLx register. When a digital microphone channel is disabled, it disables immediately and does not wait to ramp down the volume. The ADAU1787 includes four 24-bit, - ADCs with a selectable sample rate of 12 kHz to 768 kHz. 1.8V CLK DATA VDD 0.1F ADAU1787 DIGITAL MICROPHONE LEFT/RIGHT SELECT GND DMIC_CLKx DATA DMICxx DIGITAL MICROPHONE LEFT/RIGHT GND SELECT Figure 57. Digital Microphone Interface Block Diagram 20127-159 0.1F The full-scale input to the ADCs (0 dBFS) is nominally 0.49 V rms. Signal levels above the full-scale value cause the ADCs to clip. Digital ADC Volume Control The volume setting of each ADC can be digitally attenuated in the ADCx_VOL registers. The volume can be set between +24 dB and -71.25 dB in 0.375 dB steps. The ADC volume can also be digitally muted in the ADCx_MUTE bits. By default, the volume control performs a soft ramp when changed, which can be bypassed for instantaneous change of volume via the ADC_ HARD_VOL bit. The volume control for every channel can be set to use the Channel 0 volume via the ADC_VOL_LINK bit. When an ADC channel is enabled, it starts immediately at the volume level set by its ADCx_VOL register. When an ADC channel is disabled, it disables immediately and does not wait to ramp down the volume. Filtering CLK VDD ADC Full-Scale Level A high-pass filter is available on the ADC path to remove dc offsets. This filter can be enabled or disabled by using the ADCx_HPF_EN bits. The corner frequency of this high-pass filter is set to 1 Hz. The ADCxx_FCOMP bits control whether the high frequency roll-off of the decimation filter is compensated for or not. No compensation gives the lowest propagation delay but with slight attenuation in the pass-band. Rev. A | Page 36 of 280 Data Sheet ADAU1787 OUTPUT SIGNAL PATHS Data can be routed to the output DAC paths from the serial ports, the SigmaDSP core, the Fast DSP core, the ADCs, the digital microphones, or the input ASRCs. Both DAC channels must have a source at the same sample rate. The analog output pins are capable of driving headphone or earpiece speakers. The line outputs can drive a load of at least 10 k or can be put into headphone mode to drive headphones or earpiece speakers. The analog output pins are biased at the CM voltage. DACs The ADAU1787 includes two 24-bit, - DACs. These converters can operate with input sampling frequencies of 12 kHz, 24 kHz, 48 kHz, 96 kHz, 192 kHz, 384 kHz, or 768 kHz. The sample rate is selectable via the DAC_FS bit. Ensure that all channels routed to the DACs are at the same sample rate. ANALOG OUTPUTS There are two power options that trade off performance for lower power consumption in the DAC. DAC_LPM mode can set the DAC to run at a reduced oversampling ratio. The DAC_IBIAS control lowers the bias current to the DAC. Headphone Output DAC Full-Scale Level The headphone output is differential. There are two differential outputs available at HPOUTP0 and HPOUTN0 for the first output and at HPOUTP1 and HPOUTN1 for the second output. The output pins can be set as a headphone driver by setting the HPx_ MODE bits to 1 in the HP_CTRL register (Register 0xC040). The headphone outputs can drive a minimum load of at least 10 . To mute or unmute the headphone output, use the DACx_MUTE bits. The full-scale output from the DACs (0 dBFS) is nominally 1 V rms for a differential output. Line Outputs Set the output to line output mode by setting the HPx_MODE bits to 0. The analog output pins (HPOUTP0/LOUTP0, HPOUTN0/ LOUTN0, HPOUTP1/LOUTP1, and HPOUTN1/ LOUTN1) can drive differential loads of 10 k. By default, these pins are set to line output mode. To mute or unmute the line output, use the DACx_MUTE bits Pop and Click Suppression To avoid clicks and pops, mute all analog outputs that are in use while changing any register settings that may affect the signal path. These outputs can then be unmuted after the changes have been made. Digital DAC Volume Control and Filtering The volume of each DAC channel can be digitally attenuated using the DACx_VOL registers. The volume can be set to be between +24 dB and -71.25 dB in 0.375 dB steps. The DAC volume can also be digitally muted in the DACx_MUTE bits. By default, the volume control performs a soft ramp when changed, which can be bypassed for instantaneous change of volume via the DAC_ HARD_VOL bit. The volume control for both channels can be set to use the Channel 0 volume via the DAC_VOL_LINK bit. When a DAC channel is enabled, it starts at the lowest volume setting and ramps, if DAC_HARD_VOL = 0, to the volume level set by the corresponding DACx_VOL register. When a DAC channel is disabled, it ramps the volume from its current setting, if DAC_ HARD_VOL = 0, to mute and then turns off. A high-pass filter is available on the DAC path to remove dc offsets. This filter can be enabled or disabled using the DACx_ HPF_EN bits. The corner frequency of this high-pass filter is set to 1 Hz. The DAC linear interpolation filter can be selected via the DAC_MORE_FILT bit in Register 0xC03A. Setting DAC_ MORE_FILT = 0 results in lower propagation delay at the expense of lower attenuation of out of band components. Rev. A | Page 37 of 280 ADAU1787 Data Sheet PDM OUTPUTS ASRCs The ADAU1787 includes two channels of high performance, 1-bit PDM outputs suitable for driving an external amplifier or other peripheral with low latency. These PDM outputs can operate with input sampling frequencies of 12 kHz, 24 kHz, 48 kHz, 96 kHz, 192 kHz, 384 kHz, or 768 kHz. The sample rate is selectable via the PDM_FS bit. Ensure that all channels routed to the PDM outputs are at the same sample rate. The ADAU1787 includes ASRCs to enable asynchronous fullduplex operation of the serial ports. Four channels of ASRC are available for the digital outputs, and four channels of ASRC are available for the digital input signals. The PDM output modulators can run either at 3.072 MHz or 6.144 MHz, which is selected via the PDM_RATE bit. This bit also determines the rate of the PDM output clock. ASRCI can receive its inputs from one of the serial audio ports via the ASRCI_SOURCE bit. Each channel of the input ASRC can select its source from any of the 16 channels on the selected serial audio port via the ASRCIx_ROUTE bits. The output (internal) sample rate of the input ASRC is set via the ASRCI_OUT_FS bit. The PDM output is sent over a 2-wire (PDM clock and PDM data) dual data rate interface. These two signals can be routed to any multipurpose (MPx) pin output via the respective MPx_MODE bits for each pin. PDM Outputs Full-Scale Level The full-scale PDM input results in the full-scale PDM outputs. The PDM modulator performance reduces at an output amplitude greater than -7.5 dBFS. PDM Outputs Volume Control and Filtering The volume of each PDM channel can be digitally attenuated using the PDM_VOLx registers. The volume can be set to be between +24 dB and -71.25 dB in 0.375 dB steps. The PDM volume can also be digitally muted in the PDMx_MUTE bits. By default, the volume control performs a soft ramp when changed, which can be bypassed for instantaneous change of volume via the PDM_ HARD_VOL bit. The volume control for both channels can be set to use the Channel 0 volume via the PDM_VOL_LINK bit. When a PDM channel is enabled, it starts at the lowest volume setting and ramps, if PDM_HARD_VOL = 0, to the volume level set by its PDM_VOLx register. When a PDM channel is disabled, it ramps the volume from its current setting, if PDM_HARD_VOL = 0, to mute and then turn off. A high-pass filter is available on the PDM path to remove dc offsets. This filter can be enabled or disabled by using the PDMx_HPF_EN bits. The corner frequency of this high-pass filter is set to 1 Hz. The order of the final interpolation filter can be selected via the PDM_MORE_FILT bit. Selecting the lower order filter results in lower propagation delay at the expense of lower attenuation of out of band components. The ASRCs can convert serial output data from the internal rate of up to 192 kHz back down to less than 8 kHz. All intermediate frequencies and ratios are also supported. The output ASRC channels can receive their inputs from many internal sources via the ASRCOx_ROUTE bits. Ensure that the sample rate of all sources to all of the channels of the output ASRC are at the same sample rate. The source of Channel 0 determines the internal sample rate of the output ASRC. The source of the channels to the output ASRC are set via the ASRCOx_ROUTE bits. The output sample rate of the output ASRC must be linked to one of the serial ports and can be selected via the ASRCO_SAI_SEL bit. The input and output ASRCs are fully independent and can operate on different serial ports. The ASRCs automatically mute their outputs to zero data when the outputs are not locked. The state of each ASRC lock can be monitored via the ASRCI_LOCK and ASRCO_LOCK read only status bits. In addition, unlocked to locked or locked to unlocked transitions of each ASRC can be used as an interrupt source to the two interrupt controllers. By default, the ASRCs use the high performance mode of operation. A lower power, lower performance mode of operation can be enabled via each ASRCs ASRCx_LPM bit control. Additional filtering options are available to further customize the ASRCs to any application. Each ASRC has a ASRCx_VFILT bit that can enabled a voice band filter that provides additional rejection at the Nyquist frequency, which can be useful when using traditional voice band sampling frequencies. There is also an ASRCx_MORE_FILT control bit for each ASRC that provides additionally filtering of out of band energy and may improve performance in some conditions. Rev. A | Page 38 of 280 Data Sheet ADAU1787 INTERPOLATION AND DECIMATION BLOCKS The ADAU1787 includes blocks designed to convert audio from the fast sampling rate used for noise cancelling and the slow audio rate of the audio source. There are eight channels of fast to slow decimation and eight channels of slow to fast interpolation. Every two channel pairs of each block can independently operate at different input and output rates than the other two channel pairs. Ensure that the sampling rate of each two channel pair inputs matches when selecting the inputs via the routing register controls. The input sampling rates are determined by the FDECxx_IN_FS and FINTxx_IN_FS bits and the output sampling rates are determined by the FDECxx_OUT_FS and FINTxx_OUT_FS bits. For the interpolation block, the output rate must be set higher than the input rate. For the decimation block, the output rate must be set lower than the input rate. SIGNAL LEVELS Full-scale digital or 0 dBFS maps to the analog full-scale of the various converters. The SigmaDSP and FastDSP cores can maintain up to 24 dBFS internally but clip symmetrically to 0 dBFS at their outputs. By default, there is no gain adjustment between any block. Rev. A | Page 39 of 280 ADAU1787 Data Sheet FastDSP CORE The ADAU1787 FastDSP core is optimized for ANC processing. The processing capabilities of the core include biquad filters, limiters, expanders, multipliers, bit wise operations, clippers, volume controls, and weighted mixing. The core has inputs from all sources and sixteen outputs. The core is controlled with a 27-bit program word, with a maximum of 64 instructions per frame. Each instruction can always execute or conditionally execute based on an individual flag or other states. The other states include the following: INSTRUCTIONS A complete list of instructions and processing blocks can be found in the SigmaStudio software for the ADAU1787. The available instructions include the following: Single precision (27-bit fractional precision) biquad/second-order filters Double precision (54-bit fractional precision) biquad/second-order filters Lower precision (19-bit fractional precision) biquad/second-order filters Two to four input addition T connection in SigmaStudio Limiter with/without external detector loop or side chain input Expander with/without external detector loop or side chain input Linear gain Volume slider Mute Two input multiply Two to four input scale and mix Symmetrical clipper Absolute value Shift OR, AND, XOR, and INV Memory read or write FILTER PRECISION Different levels of fractional precision are available for filters in the FastDSP core. Using lower fractional precision results in lower power consumption than using higher precision. However, care must be taken to ensure that filters have enough precision to maintain stability. The logic state of MPx pins (MP0 to MP10), if used as GPIOs. The state of the output MPx pin can be set in Register 0xC092 and Register 0xC093 or SigmaDSP. The FDSP_REG_COND0 to FDSP_REG_COND7 bits are set high or low. The Modulo N counter equals zero. The GPIOs can be used on any unused MPx pins. The state of the MPx pins used as GPIOs determines whether or not an instruction executes. The FDSP_REG_CONDx bits are read/write bits that can be accessed via any of the control interfaces or via the SigmaDSP. The state of these registers determines whether or not an instruction executes. The Modulo N counter is a counter that increments every frame of the FastDSP. The counter is reset to 0 after the number of frames is set in the FDSP_MOD_N bit. Instructions can execute every N frames set by the FDSP_MOD_N bit, which provides a mechanism to easily run some instructions at a lower rate than the frame rate. When an instruction does not execute based on a condition, the instruction can be set to either do nothing or pass its input to its output. INPUT SOURCES Any instruction can use any of the following as an input source: any data register, any accumulator register, any serial port input channel, any digital microphone input, any ADC input, any SigmaDSP output, any ASRCI channel, or any output from the interpolation block. The frame rate of the FastDSP must be set and determines when the program counter starts counting again at 0, which must be set to the sample rate of the fastest source. The source that the frame rate is determined by is set via the FDSP_RATE_ SOURCE bits. If desired, the frame rate can be set independent of any source, and the rate can be set via the FDSP_RATE_DIV bits. FLAGS AND CONDITIONAL EXECUTION Several flags can be set or not set on a per instruction basis. These flags are set based on the output of that instruction. These flags include the following: Accumulator overflow Output equals zero Output is not equal to zero Output is greater than zero Output is less than zero Output is greater than or equal to zero Output is less than or equal to zero Rev. A | Page 40 of 280 Data Sheet ADAU1787 POWER AND RUN CONTROL PARAMETER BANK SWITCHING All program, parameter, and data memories for the FastDSP can be read or written from any control interface or the SigmaDSP when POWER_EN = 1, FDSP_EN = 1, and the PLL is locked, if in use. Three banks of parameters are available: A, B, and C. At any given time, the FastDSP uses only one of these banks. The three banks allow coefficients for filters and variables for other instructions to easily be switched between different processing scenarios. The bank used is selected with the FDSP_BANK_SEL bits. A single register FDSP_EN powers up the FastDSP core to allow access to the memories. The FastDSP core starts processing when both FDSP_EN = 1 and FDSP_RUN = 1. DATA MEMORY The ADAU1787 FastDSP datapath is 28 bits (5.23 format) and up to 24 dBFS is allowed. All inputs and outputs to FastDSP are 24 bits (1.23 format). The outputs are truncated to 24 bits so >0 dBFS on an output results in clipping. The data memory is 64 words. The double length memory enables the core to perform double precision arithmetic with double length data and single length coefficients. Each instruction has four associated data/state memory locations. These locations can read at any time via the I2C or SPI or from the SigmaDSP. PARAMETERS Parameters, such as filter coefficients, limiter settings, and volume control settings, are saved in parameter memories. Each parameter is a 32-bit number. The format of this number depends on the associated instruction. The number formats of the different parameters are shown in Table 16 for the biquad instructions. When the parameter formats use less than the full 32-bit memory space, as with the limiter parameters, the data is LSB aligned. Table 16. Parameter Number Format Parameter Type Filter Coefficient (B0, B1, B2, A1, A2) Format 5.27 There are three parameter banks available. Each bank can hold a full set of 320 parameters (64 filters x 5 coefficients). Users can switch between Bank A, Bank B, and Bank C, allowing three sets of parameters to be saved in memory and switched on-the-fly while the core is running. Bank switching can be achieved by writing to the FDSP_BANK_SEL bits. Parameters in the active bank must only be updated via the FastDSP safeload registers while the core is running. If parameters are not updated in this way, a bad output likely results. Parameters are assigned to instructions in the order in which the instructions are instantiated in the code. When the current bank is changed, the parameter values used for processing can either be changed on the next frame start or ramped via linear interpolation between the previously selected bank and the new bank indicated via the FDSP_BANK_SEL bits. To select this change or ramp, use the FDSP_RAMP_MODE bit. When the linear parameter ramp mode is selected, only the parameters associated with the three biquad instructions ramp. All parameters associated with other instructions change at the beginning of the next frame. Parameters in banks that are actively ramping do not change during a bank switch. It is possible to stop the linear ramp of parameters between the two values in the previous and current bank. The FDSP_LAMBDA bits are a 6-bit value representing the point along the linear interpolation curve between the two banks at which the bank ramp switch stops. The lambda value can be updated on-the-fly via the control interfaces but only increased after a ramped bank switch is initiated. To complete a bank switch, set a value of 63 (default setting). The actual current ramp point (0 to 63) can be read via the FDSP_CURRENT_LAMBDA bits. When this value reaches 63, the bank switch is complete, and the current parameters used match the current bank. Parameters in the two banks being ramped between cannot be modified while a ramped bank switch is occurring. An interrupt can be triggered to either interrupt controller via the IRQx_PRAMP interrupt source bits. This interrupt triggers on the first frame when a ramped bank switch is active and FDSP_CURRENT_LAMBDA equals FDSP_LAMBDA. The rate at which the ramp between the two banks occurs is selectable via the FDSP_RAMP_RATE bits. PARAMETER BANK COPYING The parameters of any bank can be copied to any other bank with a single control write. There are six registers, FDSP_COPY_xy, for the six possible bank copy operations. Writing a 1 to one of these bits initiates a bank copy. After a bank copy initiates, the FastDSP waits until the start of the next frame, and then during the next frame copies the content of the banks while the associated instruction is executing. The bank copy completes at the start of the subsequent frame and takes at most two frames to complete from the initiation. Copying to the active bank is not permitted but results in no action being taken. Rev. A | Page 41 of 280 ADAU1787 Data Sheet Table 17.

Reads of unused parameter banks from the I2C, SPI, or SigmaDSP are unrestricted if the FastDSP core is enabled and running. While the core is running, if the I2C, SPI, or SigmaDSP try to access the same location on the same cycle, the SigmaDSP has priority, and the read from the I2C or the SPI returns all 0s. The parameter memory for a single instruction can be updated in real time on the active bank via the safeload mechanism over the control interface. Set the instruction number in the FDSP_SL_ADDR register, set the parameter values in the FDSP_SL_Py_x registers, and write a 1 to the FDSP_SL_UPDATE register. After these settings and write occur, all parameters for that instruction are updated at the same time with the values in the FDSP_SL_Py_x registers at the beginning of the next frame. Direct reads of in use banks from the I2C or the SPI, mREAD instruction, or SigmaDSP are not allowed and return 0s. A read of the current bank returns all 0s. Writes to all parameter banks are possible when the FastDSP core is enabled but not running. Writes to unused banks are possible at any time. While the core is running, if the I2C, SPI, or SigmaDSP try to write to the same location on the same cycle, the SigmaDSP has priority, and the write from the I2C or the SPI does not occur. There is a second FastDSP safeload interface that is mapped to the data memory space of the SigmaDSP, which allows the SigmaDSP to have word addressable access. Rev. A | Page 42 of 280 Data Sheet ADAU1787 SigmaDSP CORE The ADAU1787 has an integrated SigmaDSP core that provides audio signal processing functions for improving the performance of the playback system. The signal processing flow is designed using the SigmaStudio programming environment, which allows graphical schematic entry and real-time control of all signal processing functions and registers. DATA SOURCE (DATA RAM, ROM CONSTANTS, AUDIO INPUTS) COEFFICIENT SOURCE (PARAMETER RAM, ROM CONSTANTS) 28 The SigmaDSP core does not begin a processing frame until it receives a go signal from the go source. The go signal is sent to the SigmaDSP after the signal is present at the go source. Set the go source by using the SDSP_RATE_SOURCE bits. Set the SDSP_RUN bit to 1 to enable the SigmaDSP core to run after it receives a go signal. 28 56 28 TRUNCATOR 56 56 DATA OPERATIONS (ACCUMULATORS (3), dB CONVERSION, BIT OPERATORS, BIT SHIFTER, ...) By default, with SDSP_SPEED = 0, the core runs at 24.576 MHz, giving 512 cycles of processing per each 48 kHz sample period. With SDSP_SPEED = 1, the core runs at 49.152 MHz, giving 1022 cycles of processing at 48 kHz. 56 TRUNCATOR Signal Processing Details The DSP core consists of a simple 56-bit multiply accumulate (MAC) unit with two sources: data and coefficient. The data source can come from the data RAM, a read only memory (ROM) table of commonly used constant values, or the audio inputs to the core. The coefficient source can come from the parameter RAM or from a ROM table of commonly used constant values. The two sources are multiplied in a 28-bit fixed point multiplier and the signal is then input to the 56-bit adder. The result is stored in one of three 56-bit accumulator registers. The accumulators can be output from the core in 28-bit format or can optionally be written back into the data or parameter RAMs. OUTPUTS 20127-063 28 Standard library algorithms perform fixed point calculations in either 28-bit single precision or 56-bit double precision. The input and output word lengths of the DSP core are 24 bits, but the signals inside the core are extended automatically to 28 bits to create processing headroom. This headroom allows internal gains of up to 24 dB without clipping. Additional gains can be achieved by initially scaling down the input signal in the DSP signal flow. The DSP core output is 24 bits. Therefore, linear scaling, compression, or limiting may be necessary to prevent clipping on the output. Figure 58. Simplified DSP Core Architecture Program Counter The execution of instructions in the core is governed by a program counter, which sequentially steps through the addresses of the program RAM. The program counter starts every time a start pulse signal is received. The start pulse signal occurs every time a new audio sample is received by the functional block, generating the start pulse. The source of the start pulse is selected by the SDSP_RATE_SOURCE control bits. SigmaStudio inserts a jump to start command at the end of every program. The program counter increments sequentially until the counter reaches the jump to start command and then jumps to the program start address and waits for the next audio frame to clock into the core. Watchdog The SigmaDSP watchdog is a feature that monitors the amount of instructions used in the DSP and checks against an instruction limit set by the user. If the amount of instructions that are executed in the DSP exceeds this limit, the watchdog can notify other ICs in the system via an MPx pin. Enable the watchdog via the SDSP_WDOG_EN bit in the SDSP_CTRL3 register. Set the value using the SDSP_WDOG_ VAL bits in the SDSP_CTRL4 through SDSP_CTRL6 registers. The SigmaDSP watchdog error is reported in DSP_STATUS register (Register 0xC0AE). Rev. A | Page 43 of 280 ADAU1787 Data Sheet Features The SigmaDSP core architecture is designed specifically for audio processing and, therefore, includes several features that maximize processing efficiency. Hardware accelerators, such as decibel conversion, trigonometric tables, and audio specific ROM constants provide improved processing power and simplified algorithm coding. Numeric Formats DSP systems commonly use a standard numeric format. Fractional numeric systems are specified by an AB format, where A is the number of bits to the left of the decimal point, and B is the number of bits to the right of the decimal point. The ADAU1787 uses the Numeric Format 5.23 for both the parameter and data values. Numeric Format 5.23 The linear range of the ADAU1787 numeric format is -16.0 to +16.0 - 1 LSB. For example, 1000 0000 0000 0000 0000 0000 0000 = -16.0 1110 0000 0000 0000 0000 0000 0000 = -4.0 1111 1000 0000 0000 0000 0000 0000 = -1.0 1111 1110 0000 0000 0000 0000 0000 = -0.25 1111 1111 0011 0011 0011 0011 0011 = -0.1 1111 1111 1111 1111 1111 1111 1111 = +1 LSB below 0 0000 0000 0000 0000 0000 0000 0000 = +0 0000 0000 1100 1100 1100 1100 1101 = +0.1 0000 0010 0000 0000 0000 0000 0000 = +0.25 0000 1000 0000 0000 0000 0000 0000 = +1.0 0010 0000 0000 0000 0000 0000 0000 = +4.0 0111 1111 1111 1111 1111 1111 1111 = +16.0 - 1 LSB The device can be programmed using the SigmaStudio graphic tool provided by Analog Devices. No knowledge of writing line level DSP code is required. More information about SigmaStudio is available at www.analog.com/SigmaStudio. READ/WRITE DATA FORMATS The read/write formats of the control port are byte oriented to allow ease of programming of common microcontrollers. To fit the data into a byte oriented format, 0s are added to the data fields before the MSB to extend the data-word to a full 8 bits. For example, 28-bit words written to the parameter RAM are preceded by four leading 0s to create a 32-bit (4-byte) word, and 39-bit words written to the program RAM are preceded by one leading 0 to create a 40-bit (5-byte) word. These zero padded data fields are appended to a 3-byte field that consists of a 7-bit chip address, a read/write bit, and a 16-bit RAM/register address. The control port knows how many data bytes to expect based on the address given in the first three bytes. The total number of bytes for a single location write command can vary from one byte (for a control register write) to five bytes (for a program RAM write). Use burst mode to fill the contiguous register or RAM locations. A burst mode write begins by writing the address and data of the first RAM or register location to be written to. Rather than ending the control port transaction (by issuing a stop command in I2C mode or by bringing the SS signal high in SPI mode after the data-word), as in a singleaddress write, the next data-word can be written immediately without specifying its address. The ADAU1787 control port auto-increments the address of each write even across the boundaries of the different RAMs and registers. Burst mode is outlined in the respective control port sections. The serial port accepts up to 24 bits on the input and is sign extended to the full 28 bits of the DSP core. Programming On power-up, the ADAU1787 must be configured with a clocking scheme and then loaded with register settings. After the codec signal path is set up, the DSP core can be programmed. With a 48 kHz sample rate, the internal clock rate is 49.152 MHz, resulting in 1024 instruction cycles per audio sample rate. Rev. A | Page 44 of 280 Data Sheet ADAU1787 SOFTWARE SAFELOAD To update parameters in real time while avoiding pop and click noises on the output, the ADAU1787 uses a software safeload mechanism. The software safeload mechanism enables the SigmaDSP core to load new parameters into the RAM while guaranteeing that the parameters are not in use. The use of this mechanism prevents an undesirable condition where an instruction executes with a mix of old and new parameters. SigmaStudio sets up the necessary code and parameters automatically for new projects. The safeload code, along with other initialization codes, fills the first 39 locations in the program RAM. The first eight parameter RAM locations (Address 0x0000 to Address 0x0007) are configured by default in SigmaStudio as described in Table 18. Table 18. Software Safeload Parameter RAM Defaults Address (Hex) 0x0000 0x0001 0x0002 0x0003 0x0004 0x0005 0x0006 0x0007 Function Modulo RAM size Safeload Data 1 Safeload Data 2 Safeload Data 3 Safeload Data 4 Safeload Data 5 Safeload target address (offset of -1) Number of words to write/safeload trigger Address 0x0000, which controls the modulo RAM size, is set by SigmaStudio and is based on the dynamic address generator mode of the project. Parameter RAM Address 0x0001 to Address 0x0005 are the five data slots for storing the data for safe loading. The safeload parameter space contains five data slots by default because most standard signal processing algorithms have five parameters or less. Address 0x0006 is the safeload target address in the RAM (with an offset of -1) parameter, which designates the first address to be written. If more than one word is written, the address increments automatically for each data-word. Up to five sequential parameter RAM locations can be updated with safeload during each audio frame. The target address offset of -1 is used because the write address is calculated relative to the address of the data, which starts at Address 0x0001. Therefore, to update a parameter at Address 0x000A, the target address is 0x0009. Address 0x0007 designates the number of words to be written to the RAM parameter during the safeload. A biquad filter uses all five safeload data addresses. A simple mono gain cell uses only one safeload data address. Writing to Address 0x0007 also triggers the safeload write to occur in the next audio frame. The safeload mechanism is software based and executes once per audio frame. Therefore, take care when designing the communication protocol. A delay equal to or greater than the sampling period (the inverse of sampling frequency) is required between each safeload write. A sample rate of 48 kHz equates to a delay of at least 21 s. If this delay is not observed, the downloaded data is corrupted. FastDSP SAFELOAD There are five memory locations mapped to the data memory of the SigmaDSP that can be used to update the current bank parameters of a single instruction of the FastDSP. The functionality of this is the same as the functionality of the FastDSP safeload via the control port (refer to the FastDSP Parameter Safeload section). The difference is that the parameters can be addressed on a 32-bit word basis, making the writes more efficient than reusing the control port fast load mechanism that is byte addressable. The parameters are also written to the FastDSP as soon as the frame executes, without needing to write a trigger bit. Table 19 lists the SigmaDSP assembler names for the functions used for safeload. Table 19. SigmaDSP Safeload to the FastDSP Current Bank Name FDSP_SL_ADDR FDSP_SL_P0 FDSP_SL_P1 FDSP_SL_P2 FDSP_SL_P3 FDSP_SL_P4 Rev.

Table 20 shows the RAM map. The memory map from the perspective of the SigmaDSP is different than the mapping of the memories to the external control interface because internally within the SigmaDSP each word has its own address, while over the control interface, each byte has its own address. Additionally, the mapping of the memories to the external control interface is offset. The program RAM and parameter RAM are not initialized on power-up and are in an unknown state until the RAMs are written to. PROGRAM RAM The program RAM contains the 39-bit operation codes that are executed by the core. The SigmaStudio compiler calculates the instructions executed per frame for a given program and generates an error when this number exceeds the maximum allowable instructions per frame based on the sample rate of the signals in the core. Because the end of a program contains a jump to start command, the unused program RAM space does not need to be filled with no operation (NOP) commands. PARAMETER RAM The parameter RAM is 28-bits wide and occupies Address 0 (0x0000) to Address 1023 (0x3FFF). The data format of the parameter RAM is twos complement, 5.23, which means that the coefficients can range from +16.0 (minus 1 LSB) to -16.0, with 1.0 represented by the binary word 0000 1000 0000 0000 0000 0000 0000 or by the hexadecimal word 0x00 0x80 0x00 0x00. The parameter RAM can be written to directly or with a safeload write. The direct write mode of operation is typically used during a completely new loading of the RAM using burst mode addressing to avoid any clicks or pops in the outputs. Although this mode can be used during program execution, there is no handshaking between the core and the control port, and the parameter RAM is unavailable to the DSP core during control writes, resulting in pops and clicks in the audio stream. SigmaStudio automatically assigns the first eight positions to safeload parameters. Therefore, project specific parameters start at Address 0x0008. The SDSP_RUN bit (Bit 0, Register 0xC081) must be set to 0 before writing to the parameter RAM. DATA RAM The ADAU1787 data RAM stores audio data-words for processing, as well as certain run-time parameters. SigmaStudio provides the data and address information for writing to and reading from the data RAM. The ADAU1787 has 2048 words of data RAM available. The SigmaStudio compiler manages the data RAM and indicates whether the number of addresses needed in the design exceeds the maximum number available. Table 20.

The DACs offer two separate, selectable low power operating modes, allowing power vs. performance trade-offs when using the DACs. Generally, using the DAC_LPM = 1 setting provides the same of slightly better performance at slightly lower power consumption. ADC Bias Current Control The ADCs provide a mechanism to modify the bias current level used, allowing performance vs. power consumption options for the user. Four possible settings can be set independently for Channel 0, Channel 1, Channel 2, and Channel 3 via the ADCxx_IBIAS and ADCxx_IBIAS control bits. Both low power settings also produce more part to part variation in the performance parameters than normal power mode. PLL Bypass Bypassing the PLL saves power. If the 24.576 MHz external clock is available and >25 MIPs operation of the SigmaDSP is not needed, there is no downside to bypassing the PLL.

The ADAU1787 has a 4-wire SPI control port and a 2-wire I2C bus control port. Each port can set the memories and registers. The IC defaults to I2C mode but can be put into SPI control mode by pulling the SS pin low three times. When in I2C mode, the unused control pins determine the I2C device address. The IC can be put into I2C and/or SPI mode by tying the SW_EN pin to DGND. The control port pins are multifunctional, depending on the mode in which the device is operating. Table 28 describes these multiple functions. Table 28. Control Port Pin Functions I2C Mode SCL--input SDA--open-collector output I2C Address Bit 1--input I2C Address Bit 0--input Pin SCL/SCLK SDA/MISO ADDR1/MOSI ADDR0/SS The control port is capable of full read/write operation for all addressable memories and registers. Most signal processing parameters are controlled by writing new values to the parameter memories using the control port. Other functions, such as mute and input/output mode control, are programmed through the registers. SPI Mode SCLK--input MISO--output MOSI--input SS--input BURST MODE COMMUNICATION All addresses can be accessed in either single address mode or burst mode. The first byte (Byte 0) of a control port write contains the 7-bit IC address plus the R/W bit. The next two bytes (Byte 1 and Byte 2) are the 16-bit subaddress of the memory or register location within the ADAU1787. All subsequent bytes (starting with Byte 3) contain the data, such as the register, program, or parameter data. The exact formats for specific types of writes are shown in Figure 61 and Figure 62. Burst mode addressing, in which the subaddresses are automatically incremented at word boundaries, can be used for writing large amounts of data to contiguous memory locations. This increment happens automatically after a single-word write unless the control port communication is stopped (that is, a stop condition is issued for I2C, or SS is brought high for SPI). The registers and RAMs in the ADAU1787 range in width from one byte to five bytes, so the auto-increment feature knows the mapping between subaddresses and the word length of the destination register (or memory location). If large blocks of data must be downloaded to the ADAU1787 DSP cores, the output of the cores can be disabled, new data can be loaded, and the core can then be restarted. This restart is typically done during the booting sequence at start-up or when loading a new program into memory. Table 29.

While each byte occupies a single address when communicating over a control interface (I2C or SPI), when writing to these memories, an entire memory word must be written starting with the lowest address and continuing sequentially to the highest address for a write to actually occur. Similarly, a read must begin at the lowest memory address. However, for reads, all locations must not be read. The mapping of bytes over the control interface is the most significant byte, or a memory location is written or read first, and the least significant byte is written or read last. The memories can be read or written in burst mode or single byte mode so that the proceeding requirements are met. Table 31.

I2C uses two pins, serial data (SDA) and serial clock (SCL), to carry data between the ADAU1787 and the system I2C master controller. In I2C mode, the ADAU1787 is always a slave on the bus, except when the IC is self booting. See the Self Boot section for details about using the ADAU1787 in self boot mode. The device supports fast mode plus I2C operation, but for most bus capacitances, the SDA_MISO_DRIVE bit must be set to 1 to support these operating speeds. Each slave device is recognized by a unique 7-bit device address. The ADAU1787 I2C address format is shown in Table 32. The LSB of this first byte sent from the I2C master sets either a read or write operation. Logic Level 1 corresponds to a read operation, and Logic Level 0 corresponds to a write operation. Pin ADDR0 and Pin ADDR1 set the LSBs of the I2C address (see Table 33). Therefore, each ADAU1787 can be set to one of four unique addresses, allowing multiple ICs to exist on the same I2C bus without address contention. The 7-bit I2C addresses are shown in Table 33. An I2C data transfer is always terminated by a stop condition. Both SDA and SCL must have 2.0 k pull-up resistors on the lines connected to these pins. The voltage on these signal lines cannot be higher than IOVDD. Table 32. I2C Address Format Bit 6 0 Bit 5 1 Bit 4 0 Bit 3 1 Bit 2 0 Bit 1 ADDR1 Bit 0 ADDR0 Table 33. I2C Addresses ADDR1 (MOSI) 0 0 1 1 ADDR0 (SS) 0 1 0 1 Slave Address 0x28 0x29 0x2A 0x2B Addressing Initially, each device on the I2C bus is in an idle state and monitoring the SDA and SCL lines for a start condition and the proper address. The I2C master initiates a data transfer by establishing a start condition, defined by a high to low transition on SDA while SCL remains high, indicating that an address/data stream follows. All devices on the bus respond to the start condition and shift the next eight bits (the 7-bit address plus the R/W bit) MSB first. The device that recognizes the transmitted address responds by pulling the data line low during the ninth clock pulse. This ninth bit is known as an acknowledge bit. All other devices withdraw from the bus at this point and return to the idle condition. The R/W bit determines the direction of the data. A Logic 0 on the LSB of the first byte indicates that the master writes information to the peripheral, whereas a Logic 1 indicates that the master reads information from the peripheral after writing the subaddress and repeating the start address. A data transfer takes place until a stop condition is encountered. A stop condition occurs when SDA transitions from low to high while SCL is held high. Figure 59 shows the timing of an I2C write, and Figure 60 shows an I2C read. Stop and start conditions can be detected at any stage during the data transfer. If these conditions are asserted out of sequence with normal read and write operations, the ADAU1787 immediately jumps to the idle condition. During a given SCL high period, the user can only issue one start condition, one stop condition, or a single stop condition followed by a single start condition. A noacknowledge condition is where the SDA line is not pulled low on the ninth clock pulse on SCL. If an invalid subaddress is issued by the user, the ADAU1787 issues an acknowledge, but no data write occurs, and a read returns zeros. If the highest subaddress location is reached while in write mode, the data for the invalid byte is not loaded to any subaddress register. Rev.

The master then responds every ninth pulse with an acknowledge pulse to the ADAU1787. Figure 61 shows the timing of a single-word write operation. Every ninth clock pulse, the ADAU1787 issues an acknowledge by pulling SDA low. Figure 64 shows the timing of a burst mode read sequence. Figure 64 shows an example where the target read words are two bytes. The ADAU1787 increments its subaddress every two bytes because the requested subaddress corresponds to a register or memory area with word lengths of two bytes. Other address ranges may have a variety of word lengths, ranging from one byte to four bytes. The ADAU1787 always decodes the subaddress and sets the auto-increment circuit so that the address increments after the appropriate number of bytes. Figure 62 shows the timing of a burst mode write sequence. Figure 62 shows an example where the target destination words are two bytes, such as the program memory. The ADAU1787 knows to increment its subaddress register every two bytes because the requested subaddress corresponds to a register or memory area with a 2-byte word length. The timing of a single-word read operation is shown in Figure 63. Note that the first R/W bit is 0, indicating a write operation because the subaddress still must be written to set up the internal address. After the ADAU1787 acknowledges the receipt of the subaddress, the master must issue a repeated start command, followed by the chip address byte with the R/W set to 1 (read), causing the ADAU1787 SDA to reverse and begin driving data I2C ADDRESS, R/W = 0 AS SUBADDRESS HIGH SUBADDRESS LOW AS AS S is the start bit.

Single-Word I2C Write Format Data Sheet ADAU1787 SPI PORT R/W 2 By default, the ADAU1787 is in I C mode, but the device can be put in SPI control mode by pulling SS low three times by issuing three SPI writes, which are in turn ignored by the ADAU1787. The next (fourth) SPI write is then latched in the SPI port. The first byte of an SPI transaction indicates whether the communication is a read or a write with the R/W bit. The LSB of this first byte determines whether the SPI transaction is a read (Logic Level 1) or a write (Logic Level 0). The SPI port uses a 4-wire interface, consisting of SS, SCLK, MOSI, and MISO signals, and is always a slave port. The SS signal must go low at the beginning of a transaction and high at the end of a transaction. The SCLK signal latches MOSI on a low to high transition. MISO data is shifted out of the ADAU1787 on the falling edge of SCLK and must be clocked to a receiving device, such as a microcontroller, on the SCLK rising edge. The MOSI signal carries the serial input data, and the MISO signal is the serial output data. The MISO signal remains tristated until a read operation is requested, allowing other SPI-compatible peripherals to share the same readback line. The 16-bit subaddress word is decoded into a location in one of the memories or registers. This subaddress is the location of the appropriate memory location or register. Subaddress It is necessary to add an unused byte of zeros after the subaddress to effectively make the subaddress 24 bits with the actual address placed in the 16 MSBs. Data Bytes The number of data bytes varies according to the register or memory being accessed. During a burst mode write, an initial subaddress is written followed by a continuous sequence of data for consecutive memory and/or register locations. All SPI transactions have the same basic format shown in Table 34. The timing diagrams for SPI write and SPI read are shown in Figure 65 and Figure 66, respectively. All data must be written MSB first. The ADAU1787 can only be taken out of SPI mode by pulling the PD pin low or by powering down the IC. A sample timing diagram for a single-write SPI operation to the parameter RAM is shown in Figure 65. A sample timing diagram of a single-read SPI operation is shown in Figure 66. The MISO pin goes from tristate to being driven at the beginning of Byte 3. In this example, Byte 0 to Byte 2 contain the addresses and the R/W bit and subsequent bytes carry the data. Table 34.

Example of Self Boot EEPROM Instructions SELF BOOT The ADAU1787 boots up from an EEPROM over the I2C bus when the SELFBOOT pin is set high at power-up and the PD pin is set high. The state of the SELFBOOT pin is checked internally only when the ADAU1787 comes out of a reset via the PD pin going high or by applying power with PD already set high. When the device comes out of reset and there is a MCLK source present, the state of the SELFBOOT pin is registered to determine whether to self boot. At reset, the state is set not to self boot. Therefore, if a master clock at the MCLKIN pin is not present, the self boot does not occur. The EEPROM is not used after a self boot completes. During booting, ensure that there is a stable DVDD in the system. The PD pin must remain high during self boot operation. If the SELFBOOT pin is not used for a multipurpose pin function, tie the pin to either IOVDD or DGND. The master SCL clock output from the ADAU1787 is derived from the input clock on XTALI/MCLKIN. A divide by 64 circuit ensures that the SCL output frequency during self boot operation is never greater than 400 kHz for most input clock frequencies. With the external master clock to the ADAU1787 being between 11.264 MHz and 27 MHz, the SCL frequency ranges from 176 kHz to 422 kHz. If the self-boot EEPROM is not rated for operation above 400 kHz, use a master clock that is no faster than 25.6 MHz. Table 35 details the list of instructions that are possible during an ADAU1787 self boot. The 0x01 and 0x05 instruction bytes are used to load the register, program, and parameter settings. EEPROM Size The self-boot circuit is compatible with an EEPROM that has a 2-byte address. For most EEPROM families, a 2-byte address is used on devices that are 32 kB or larger. The EEPROM must be set to Address 0x50. Examples of two compatible EEPROMs include Atmel AT24C256C and STMicroelectronics M24256. Table 36 lists the maximum necessary EEPROM size, assuming that there is 100% utilization. There is inherently some overhead for instructions to control the self boot procedure. CRC An 8-bit CRC validates the content of the EEPROM. This CRC is strong enough to detect single error bursts of up to eight bits in size. The terminate self boot instruction (0x00 instruction byte) must be followed by a CRC byte. The CRC is generated using all of the EEPROM bytes from Address 0x0000 to the last 0x00 instruction byte. The polynomial for the CRC is x8 + x2 + x + 1. If the CRC is incorrect or if an unrecognized instruction byte is read during self boot, the boot process is immediately stopped and restarted after a 250 ms delay (for a 12.288 MHz input clock). When SigmaStudio is used, the CRC byte is generated automatically when a configuration is downloaded to the EEPROM. Delay The delay instruction (0x02 instruction byte) delays by the 16-bit setting x 2048 clock cycles. Boot Time The time to self boot the ADAU1787 from an EEPROM can be calculated by the following equation: Self Boot Time = 64/MCLK Frequency x Total Bytes + Wait Time The self boot operation starts after 16,568 clock cycles are seen on the XTALI/MCLKIN pin after PD is set high. With a 12.288 MHz clock, this wait time corresponds to approximately a 1.35 ms wait time from power-up. This delay ensures that the crystal used for generating the master clock has ramped up to a stable oscillation. Rev. A | Page 54 of 280 ADAU1787 Data Sheet Table 36.

Multipurpose Pin Functions The ADAU1787 has thirteen multipurpose (MPx) pins that can be used for serial data I/O, digital microphone inputs, clock outputs, PDM outputs, and interrupts. Each pin can be individually set to either its default or MPx setting. The function of each of these pins is set in using the MPx_MODE bits. By default, each pin is configured as its normal function. MPx Pin Function1 Digital Microphone Channel 4 to Channel 5 Input (DMIC45) Digital Microphone Channel 6 to Channel 7 Input (DMIC67) General-Purpose Input (GPI) General-Purpose Output from GPIOx_OUT Bits (GPO_REG) General-Purpose Output from SigmaDSP (GPO_SDSP) MCLK Output (MCLKO) IRQ1 Output (IRQ1) IRQ2 Output (IRQ2) Care must be taken when using SELFBOOT/MP11 and SW_EN/MP12 as multipurpose pins. The states of these pins at power-up (later of either PD pin going high or power being applied with PD pin already high) determine whether the device self boots, which must still be followed even if the pins are used for another multipurpose function later. When an MPx pin is set as a general-purpose input, the MPx pin can be read via all control interfaces via the GPIOx_IN bits, the pin can also be read and acted upon by the SigmaDSP core, and the pin can be used to conditionally execute instructions or trigger the compressor in the FastDSP. When an MPx pin is set as general-purpose output, the state of the pin can be set via all control interfaces using the GPIOx_OUT bits or by the SigmaDSP core. The GPIO maps to the corresponding MPx pin, for example, GPIO1 maps to MP1/BCLK_0. Any MPx pin can be used as the digital microphone input for Digital Microphone Channel 4/ Digital Microphone Channel 5 or Digital Microphone Channel 6/ Digital Microphone Channel 7. If multiple pins are assigned to this function, the lowest number MPx pin is used, and the other pins have no function. Any MPx pin can be used as a master clock output. The rate of the master clock output is determined by the MCLKO_RATE bits. Multiple pins can be used as this function if desired. Any MPx pin can be used to output the PDM clock or data signal for the PDM output interface. Any MPx pin can be used to output the interrupt status from the two interrupt sources. 1 Direction In In In Out Out Out Out Out These functions are enumeration options in Register 0xC08B through Register 0xC090 that any of the MPx pins can be set to. Interrupts Each multipurpose pin can be used to output one of two interrupts that have various sources when selected for this function. The sources for the interrupts are for DAC and ADC channels clipping, PLL locking or unlocking, input and output ASRCs locking or unlocking, the generic SigmaDSP interrupts, and the AVDD undervoltage warning. Each interrupt source can be individually masked with their respective IRQx_MASKx registers. Each interrupt output can be set to active low or active high output on the pin selected for the interrupt output via the IRQx_FUNC bits. The status of each interrupt source can be read via the IRQ status registers (IRQx_STATUSx). When an interrupt source is masked, if that interrupt becomes true, the interrupt is shown in the interrupt status registers but does not cause the MPx pin (if set as IRQx) to show an interrupt. All sources of each interrupt are cleared via a write of 1 to the IRQx_CLEAR bits. The interrupt status bits are sticky, such that if an interrupt source becomes true, the status reads 1 until a clear occurs, even if that interrupt source is no longer true. The SigmaDSP interrupts are initiated by the SigmaDSP writing to the SDSP_INTx bits. Pin Controls Each pin that can be used as a multipurpose pin has several control selections to set various setting. When the pin is used as an output, the drive strength can be selected at 2 mA, 4 mA, 8 mA, or 12 mA. In addition, a weak pull-up or pull-down can be selected. These settings are in their respective pin control register. These pin control settings affect the pins operation in both normal functional mode and when used in all multipurpose pin modes. Rev. A | Page 56 of 280 Data Sheet ADAU1787 SERIAL DATA PORTS The serial data input and output ports of the ADAU1787 can be set to accept or transmit data in a 2-channel format such as I2S or up to 16 channels in a time division multiplexing (TDM) stream to interface to external ADCs, DACs, DSPs, and system on chips (SOCs). Data is processed in twos complement, MSB first format. The left channel data field always precedes the right channel data field in 2-channel streams. When using a high bit clock rate (12.288 MHz or higher), it is recommended to increase the drive strength settings for the output signal pins. The high drive strength effectively speeds up the transition times of the waveforms, thereby improving the signal integrity of the clock and data lines. The drive strength can be set in the pad drive strength registers (Register 0xC094 through Register 0xC0A0). The serial data clocks do not need to be synchronous with the ADAU1787 master clock input, but the frame clock and bit clock must be synchronous to each other. The FSYNC_x and BCLK_x pins are used to clock both the serial input and output ports. The pins can also be used as a source to the PLL to provide the main chip clock. Each serial port can be set to be either the master or the slave in a system. Because there is only one set of serial data clocks, the input and output of a single port must always both be either master or slave. Table 38 describes the proper serial port settings for standard audio data formats. More information about the settings in Table 38 can be found in the SPTx_CTRLx register descriptions. The SPTx_SAI_MODE bits set whether the serial port is operating in stereo mode or TDM mode. In stereo modes, both edges of frame clock determine where data is placed, and the left channel maps to the output for Channel 0, while the right channel maps to the output for Channel 1. In TDM mode only, the rising edge of frame clock determine where data is placed. In TDM mode, each channel of data receives a slot that can be either 16, 24, or 32 BCLKs wide. The width of each slot is determined by the SPTx_SLOT_WIDTH bits. The serial data control registers allow control of the clock polarity and the data input modes. The valid data formats are I2S (delay by 1), left justified (delay by 0), or right justified (delay by 8, 12, or 16 BCLKs). The delay indicates the number of bit clocks BCLKs from the rising/falling edge of frame clock FSYNC_x where the MSB of the data is placed in stereo modes, and the number of bit clocks BCLKs from the rising of frame clock in TDM mode. In all modes except for the right justified mode, the serial port inputs an arbitrary number of bits up to a limit of 24. Extra bits do not cause an error, but the bits are ignored. The serial port can operate with an arbitrary number of bit clock BCLK_x transitions in each frame clock frame. The polarity of both frame clock and bit clock can be inverted via the SPTx_LRCLK_POL and SPTx_BCLK_POL bits. These bits do not need to be used to support the typical formats shown in Table 38. Setting either SPTx_LRCLK_POL or SPTx_BCLK_POL to 1 places an inverter at the input to the serial port on its respective signal. For example, while serial data and frame clock are normally sampled on the rising edge of bit clock, setting SPTx_BCLK_POL = 1 samples on the falling edge of bit clock. Each serial port can be set to be a master, in which case BCLK_x and FSYNC_x are driven as outputs. The output rate and direction of these two signals are set via the SPTx_LRCLK_SRC and SPTx_BCLK_SRC bits. A bit clock rate higher than 24.576 MHz cannot be generated. Therefore, the settings of these registers that request this rate result in no bit clock. Unused bit slots can be tristated so that multiple ICs can drive a single serial data bus, which is controlled via the SPTx_TRI_ STATE bit. For example, in a 32-bit TDM frame with 24-bit data, the eight unused bits are tristated. Inactive channels are also tristated for one full frame each. Serial output channels are disabled when the SPTx_OUT_ROUTEy bits are set to 0x3E. Note that the timing for serial data output changes based on the minimum IOVDD voltage. While the serial ports can work for inputting a signal on SDATAI_x for any IOVDD and bit clock rate within the specification, the delay on SDATAO_x at 1.1 V excludes operating at higher bit clock rates.

The connections to each side of the capacitor must be as short as possible, and the trace must be routed on a single layer with no vias. For maximum effectiveness, locate the capacitor equidistant from the power and ground pins or slightly closer to the power pin if equidistant placement is not possible. Thermal connections to the ground planes must be made on the far side of the capacitor. The HPVDD supply is for the headphone amplifiers. If the headphone amplifiers are enabled, the PCB trace to this pin must be wider than the traces to other pins to increase the current carrying capacity. A wider trace must also be used for the headphone output lines. Each supply signal on the board must also be bypassed with a single bulk capacitor (10 F to 47 F). AVDD PIN AGND PIN Use a single ground plane in the application layout. Place the components in the analog signal path away from the digital signals. PCB STACKUP Figure 71 shows the PCB stackup.

FastDSP Bank Switch Ramp Stop Point. Lambda is a 6-bit value representing the point along the linear interpolation curve between two banks at which the bank ramp switch stops. 0 = ((63/64) x A + (1/64) x B), 1 = ((62/64) x A + (2/64) x B), ... , 62 = ((1/64) x A + (63/64) x B), and 63 = B (default) lambda can be updated on-the-fly via the control interface. To complete a bank switch, a value of 63 (default setting) must be set. Actual current ramp point (FDSP_CURRENT_LAMBDA: 0 to 63) can be read via a status register. When this point reaches 63, the bank switch is complete, and the current parameters used match the current bank. The actual step size of the linear interpolation is ~12 bits (4096 steps). Parameters in banks that are being ramped between must not change during a bank switch. Bank switch parameter ramp stops at 1/64 of full ramp. Bank switch parameter ramp stops at 2/64 of full ramp. ... Bank switch parameter ramp stops at 63/64 of full ramp. Bank switch parameter ramp completes ramp to current bank. Rev.

Lambda is a 6-bit value representing the point along the linear interpolation curve between two banks at which the bank ramp switch stops. 0 = ((63/64) x A + (1/64) x B), 1 = ((62/64) x A + (2/64) x B), ... , 62 = ((1/64) x A + (63/64) x B), and 63 = B (default) lambda can be updated on-the-fly via the control interface. To complete a bank switch, a value of 63 (default setting) must be set. Actual current ramp point (FDSP_CURRENT_LAMBDA: 0 to 63) can be read via a status register. When this point reaches 63, the bank switch is complete, and the current parameters used matches the current bank. Actual step size of linear interpolation is ~12 bits (4096 steps). Parameters in banks that are being ramped between should not change during a bank switch. Bank switch parameter ramp is at 1/64 of full ramp. Bank switch parameter ramp is at 2/64 of full ramp. ... Bank switch parameter ramp is at 63/64 of full ramp. Bank switch parameter ramp is complete. Rev.
