General Description The CrimzonTM ZLR16300 is a ROM-based member of the MCU family of general purpose microcontrollers. With 236B of general-purpose RAM and 4KB to 16KB of program memory, ZiLOG(R)'s CMOS microcontrollers offer fast-executing, efficient use of memory, sophisticated interrupts, input/output bit manipulation capabilities, automated pulse generation/reception, and internal key-scan pull-up transistors. The ZLR16300 architecture (Figure 1) is based on ZiLOG(R)'s 8-bit microcontroller core with an Expanded Register File allowing access to register-mapped peripherals, input/output (I/O) circuits, and powerful counter/timer circuitry. The Z8(R) core offers a flexible I/O scheme, an efficient register and address space structure, and a number of ancillary features that are useful in many consumer, automotive, computer peripheral, and battery-operated hand-held applications. There are three basic address spaces available to support a wide range of configurations: Program Memory, Register File and Expanded Register File. The register file is composed of 256B of RAM. It includes three I/O port registers, 16 control and status registers, and 236 general-purpose registers. The Expanded Register File consists of two additional register groups (F and D). To unburden the program from coping with such real-time problems as generating complex waveforms or receiving and demodulating complex waveform/pulses, the CrimzonTM ZLR16300 offers a new intelligent counter/timer architecture with 8-bit and 16-bit counter/timers (see Figure 2). Also included are a large number of user-selectable modes and two on-board comparators to process analog signals with separate reference voltages. Note: All signals with an overline, " ", are active Low. For example, B/W, in which WORD is active Low, and B/W, in which BYTE is active Low.

PS021403-0304 P r e l i m i n a r y AC Characteristics CrimzonTM ZLR16300 Z8 Low-Voltage MCUs with Infrared Timers 12 Pin Functions XTAL1 Crystal 1 (Time-Based Input) This pin connects a parallel-resonant crystal, ceramic resonator, or LC to the onchip oscillator input. Additionally, an external single-phase clock can be connected to the on-chip oscillator input. XTAL2 Crystal 2 (Time-Based Output) This pin connects a parallel-resonant, crystal, ceramic resonant, or LC to the onchip oscillator output. Port 0 (P07-P00) Port 0 is an 8-bit, bidirectional, CMOS-compatible port. These eight I/O lines are configured under software control as a nibble I/O port. The output drivers are push-pull or open-drain controlled by bit D2 in the PCON register. If one or both nibbles are needed for I/O operation, they must be configured by writing to the Port 0 mode register. After a hardware reset, Port 0 is configured (Figure 7) as an input port. An optional pull-up transistor is available as a OTP/mask option on all Port 0 bits with nibble select. Notes: Internal pull-ups are disabled on any given pin or group of port pins when programmed into Output mode. The Port 0 direction is reset to its default state following an SMR.

Port 0 Configuration Port 2 (P27-P20) Port 2 is an 8-bit, bidirectional, CMOS-compatible I/O port (see Figure 8). These eight I/O lines can be independently configured under software control as inputs or outputs. Port 2 is always available for I/O operation. A mask option is available to connect eight pull-up transistors on this port. Bits programmed as outputs are globally programmed as either push-pull or open-drain. The POR resets with the eight bits of Port 2 configured as inputs. Port 2 also has an 8-bit input OR and AND gate, which can be used to wake up the part. P20 can be programmed to access the edge-detection circuitry in Demodulation mode.

Port 2 Configuration Port 3 (P37-P30) Port 3 is an 8-bit, CMOS-compatible fixed I/O port (see Figure 9). Port 3 consists of four fixed input (P33-P30) and four fixed output (P37-P34), which can be configured under software control for interrupt and as output from the counter/timers. P30, P31, P32, and P33 are standard CMOS inputs; P34, P35, P36, and P37 are push-pull outputs.

Port 3 Configuration Two on-board comparators process analog signals on P31 and P32, with reference to the voltage on Pref1 and P33. The analog function is enabled by programming the Port 3 Mode Register (bit 1). P31 and P32 are programmable as rising, falling, or both edge triggered interrupts (IRQ register bits 6 and 7). Pref1 and P33 are the comparator reference voltage inputs. Access to the Counter Timer edgedetection circuit is through P31 or P20 (see "T8 and T16 Common Functions--"T8 PS021403-0304 P r e l i m i n a r y Pin Functions CrimzonTM ZLR16300 Z8 Low-Voltage MCUs with Infrared Timers 16 and T16 Common Functions--CTR1(0D)01h" on page 28). Other edge detect and IRQ modes are described in Table 9. Note: Comparators are powered down by entering Stop Mode. For P31-P33 to be used in a Stop Mode Recovery (SMR) source, these inputs must be placed into Digital mode. 2 Table 9.

The comparator reference is supplied to P33 and Pref1. In this mode, the P33 internal data latch and its corresponding IRQ1 are diverted to the SMR sources (excluding P31, P32, and P33) as indicated in Figure 9 on page 15. In digital mode, P33 is used as D3 of the Port 3 input register, which then generates IRQ1. Note: Comparators are powered down by entering Stop Mode. For P31-P33 to be used in a Stop Mode Recovery source, these inputs must be placed into Digital mode. Comparator Outputs These channels can be programmed to be output on P34 and P37 through the PCON register.

Instructions can access registers directly or indirectly through an 8-bit address field, thereby allowing a short, 4-bit register address to use the Register Pointer (Figure 14). In the 4-bit mode, the register file is divided into 16 working register groups, each occupying 16 continuous locations. The Register Pointer addresses the starting location of the active working register group. Note: Register address E0h-EFh can only be accessed through working registers and indirect addressing modes.

T8 Enable This field enables T8 when set (written) to 1. Single/Modulo-N When set to 0 (Modulo-N), the counter reloads the initial value when the terminal count is reached. When set to 1 (Single-Pass), the counter stops when the terminal count is reached. Timeout This bit is set when T8 times out (terminal count reached). To reset this bit, write a 1 to its location. Caution: Writing a 1 is the only way to reset the Terminal Count status condition. Reset this bit before using/enabling the counter/timers. The first clock of T8 might not have complete clock width and can occur any time when enabled. Note: Take care when using the OR or AND commands to manipulate CTR0, bit 5 and CTR1, bits 0 and 1 (Demodulation Mode). These instructions use a Read-Modify-Write sequence in which the current status from the CTR0 and CTR1 registers is ORed or ANDed with the designated value and then written back into the registers. Example When the status of bit 5 is 1, a timer reset condition occurs. PS021403-0304 P r e l i m i n a r y Functional Description CrimzonTM ZLR16300 Z8 Low-Voltage MCUs with Infrared Timers 28 T8 Clock This bit defines the frequency of the input signal to T8.

P36_Out/Capture_Input In Transmit Mode, this bit defines whether P36 is used as a normal output pin or the combined output of T8 and T16. In Demodulation Mode, this bit defines whether the input signal to the Counter/ Timers is from P20 or P31. If the input signal is from Port 31, a capture event may also generate an IRQ2 interrupt. To prevent generating an IRQ2, either disable the IRQ2 interrupt by clearing its IMR bit D2 or use P20 as the input. PS021403-0304 P r e l i m i n a r y Functional Description CrimzonTM ZLR16300 Z8 Low-Voltage MCUs with Infrared Timers 30 T8/T16_Logic/Edge_Detect In Transmit Mode, this field defines how the outputs of T8 and T16 are combined (AND, OR, NOR, NAND). In Demodulation Mode, this field defines which edge should be detected by the edge detector. Transmit_Submode/Glitch Filter In Transmit Mode, this field defines whether T8 and T16 are in the Ping-Pong mode or in independent normal operation mode. Setting this field to "Normal Operation Mode" terminates the "Ping-Pong Mode" operation. When set to 10, T16 is immediately forced to a 0; a setting of 11 forces T16 to output a 1. In Demodulation Mode, this field defines the width of the glitch that must be filtered out. Initial_T8_Out/Rising_Edge In Transmit Mode, if 0, the output of T8 is set to 0 when it starts to count. If 1, the output of T8 is set to 1 when it starts to count. When the counter is not enabled and this bit is set to 1 or 0, T8_OUT is set to the opposite state of this bit. This ensures that when the clock is enabled, a transition occurs to the initial state set by CTR1, D1. In Demodulation Mode, this bit is set to 1 when a rising edge is detected in the input signal. In order to reset the mode, a 1 should be written to this location. Initial_T16 Out/Falling _Edge In Transmit Mode, if it is 0, the output of T16 is set to 0 when it starts to count. If it is 1, the output of T16 is set to 1 when it starts to count. This bit is effective only in Normal or Ping-Pong Mode (CTR1, D3; D2). When the counter is not enabled and this bit is set, T16_OUT is set to the opposite state of this bit. This ensures that when the clock is enabled, a transition occurs to the initial state set by CTR1, D0. In Demodulation Mode, this bit is set to 1 when a falling edge is detected in the input signal. In order to reset it, a 1 should be written to this location. Note: Modifying CTR1 (D1 or D0) while the counters are enabled causes unpredictable output from T8/16_OUT.

If the initial value (CTR1, D1) is 0, TC8L is loaded; otherwise, TC8H is loaded into the counter. In Single-Pass Mode (CTR0, D6), T8 counts down to 0 and stops, T8_OUT toggles, the timeout status bit (CTR0, D5) is set, and a timeout interrupt can be generated if it is enabled (CTR0, D1). In Modulo-N Mode, upon reaching terminal count, T8_OUT is toggled, but no interrupt is generated. From that point, T8 loads a new count (if the T8_OUT level now is 0), TC8L is loaded; if it is 1, TC8H is loaded. T8 counts down to 0, toggles T8_OUT, and sets the timeout status bit (CTR0, D5), thereby generating an interrupt if enabled (CTR0, D1). One cycle is complete. T8 then loads from TC8H or TC8L according to the T8_OUT level and repeats the cycle. See Figure 17.

Transition from 0 to FFh is not a timeout condition. Caution: Using the same instructions for stopping the counter/timers and setting the status bits is not recommended. Two successive commands are necessary. First, the counter/timers must be stopped. Second, the status bits must be reset. These commands are required because it takes one counter/timer clock interval for the initiated event to actually occur. See Figure 18 and Figure 19.

T8_OUT in Modulo-N Mode T8 Demodulation Mode The user must program TC8L and TC8H to FFh. After T8 is enabled, when the first edge (rising, falling, or both depending on CTR1, D5; D4) is detected, it starts to count down. When a subsequent edge (rising, falling, or both depending on CTR1, D5; D4) is detected during counting, the current value of T8 is complemented and put into one of the capture registers. If it is a positive edge, data is put into LO8; if it is a negative edge, data is put into HI8.

Meanwhile, T8 is loaded with FFh and starts counting again. If T8 reaches 0, the timeout status bit (CTR0, D5) is set, and an interrupt can be generated if enabled (CTR0, D1).

If it is a 0, T16_OUT is a 1; if it is a 1, T16_OUT is 0. You can force the output of T16 to either a 0 or 1 whether it is enabled or not by programming CTR1 D3; D2 to a 10 or 11. When T16 is enabled, TC16H * 256 + TC16L is loaded, and T16_OUT is switched to its initial value (CTR1, D0). When T16 counts down to 0, T16_OUT is toggled (in NORMAL or PING-PONG mode), an interrupt (CTR2, D1) is generated (if enabled), and a status bit (CTR2, D5) is set. See Figure 22.

If T16 is in Single-Pass mode, it is stopped at this point (see Figure 23). If it is in Modulo-N Mode, it is loaded with TC16H * 256 + TC16L, and the counting continues (see Figure 24). The values in TC16H and TC16L can be modified at any time. The new values take effect when they are loaded.

T16_OUT in Modulo-N Mode T16 Demodulation Mode The user must program TC16L and TC16H to FFh. After T16 is enabled, and the first edge (rising, falling, or both depending on CTR1 D5; D4) is detected, T16 captures HI16 and LO16, reloads, and begins counting. If D6 of CTR2 Is 0 When a subsequent edge (rising, falling, or both depending on CTR1, D5; D4) is detected during counting, the current count in T16 is complemented and put into HI16 and LO16. When data is captured, one of the edge detect status bits (CTR1, D1; D0) is set, and an interrupt is generated if enabled (CTR2, D2). T16 is loaded with FFFFh and starts again. This T16 mode is generally used to measure space time, the length of time between bursts of carrier signal (marks). PS021403-0304 P r e l i m i n a r y Functional Description CrimzonTM ZLR16300 Z8 Low-Voltage MCUs with Infrared Timers 41 If D6 of CTR2 Is 1 T16 ignores the subsequent edges in the input signal and continues counting down. A timeout of T8 causes T16 to capture its current value and generate an interrupt if enabled (CTR2, D2). In this case, T16 does not reload and continues counting. If the D6 bit of CTR2 is toggled (by writing a 0 then a 1 to it), T16 captures and reloads on the next edge (rising, falling, or both depending on CTR1, D5; D4), continuing to ignore subsequent edges. This T16 mode generally measures mark time, the length of an active carrier signal burst. If T16 reaches 0, T16 continues counting from FFFFh. Meanwhile, a status bit (CTR2 D5) is set, and an interrupt timeout can be generated if enabled (CTR2 D1). Ping-Pong Mode This operation mode is only valid in Transmit Mode. T8 and T16 must be programmed in Single-Pass mode (CTR0, D6; CTR2, D6), and Ping-Pong mode must be programmed in CTR1, D3; D2. The user can begin the operation by enabling either T8 or T16 (CTR0, D7 or CTR2, D7). For example, if T8 is enabled, T8_OUT is set to this initial value (CTR1, D1). According to T8_OUT's level, TC8H or TC8L is loaded into T8. After the terminal count is reached, T8 is disabled, and T16 is enabled. T16_OUT then switches to its initial value (CTR1, D0), data from TC16H and TC16L is loaded, and T16 starts to count. After T16 reaches the terminal count, it stops, T8 is enabled again, repeating the entire cycle. Interrupts can be allowed when T8 or T16 reaches terminal control (CTR0, D1; CTR2, D1). To stop the ping-pong operation, write 00 to bits D3 and D2 of CTR1. See Figure 25. Note: Enabling ping-pong operation while the counter/timers are running might cause intermittent counter/timer function. Disable the counter/timers and reset the status flags before instituting this operation.

Set T8 into Single-Pass mode (CTR0, D6), set T16 into Single-Pass mode (CTR2, D6), and set the PingPong mode (CTR1, D2; D3). These instructions can be in random order. Finally, start Ping-Pong mode by enabling either T8 (CTR0, D7) or T16 (CTR2, D7). See Figure 26.

Output Circuit The initial value of T8 or T16 must not be 1. If you stop the timer and restart the timer, reload the initial value to avoid an unknown previous value. PS021403-0304 P r e l i m i n a r y Functional Description CrimzonTM ZLR16300 Z8 Low-Voltage MCUs with Infrared Timers 43 During Ping-Pong Mode The enable bits of T8 and T16 (CTR0, D7; CTR2, D7) are set and cleared alternately by hardware. The timeout bits (CTR0, D5; CTR2, D5) are set every time the counter/timers reach the terminal count. Interrupts The ZLR16300 features six different interrupts (Table 14). The interrupts are maskable and prioritized (Figure 27). The six sources are divided as follows: three sources are claimed by Port 3 lines P33-P31, two by the counter/timers (Table 14) and one for low voltage detection. The Interrupt Mask Register (globally or individually) enables or disables the six interrupt requests. The source for IRQ is determined by bit 1 of the Port 3 mode register (P3M). When in digital mode, Pin P33 is the source. When in Analog mode the output of the Stop Mode Recovery source logic is used as the source for the interrupt. See Figure 32, Stop Mode Recovery Source, on page 52.

An interrupt machine cycle activates when an interrupt request is granted. As a result, all subsequent interrupts are disabled, and the Program Counter and Status Flags are saved. The cycle then branches to the program memory vector location reserved for that interrupt. All interrupts are vectored through locations in the program memory. This memory location and the next byte contain the 16-bit address of the interrupt service routine for that particular interrupt request. To accommodate polled interrupt systems, interrupt inputs are masked, and the Interrupt Request register is polled to determine which of the interrupt requests require service. An interrupt resulting from AN1 is mapped into IRQ2, and an interrupt from AN2 is mapped into IRQ0. Interrupts IRQ2 and IRQ0 can be rising, falling, or both edge triggered. These interrupts are programmable by the user. The software can poll to identify the state of the pin. Programming bits for the Interrupt Edge Select are located in the IRQ Register (R250), bits D7 and D6. The configuration is indicated in Table 15. Table 15.

The crystal must be AT cut, 1 MHz to 8 MHz maximum, with a series resistance (RS) less than or equal to 100 . The onchip oscillator can be driven with a suitable external clock source. For 32-kHz crystal operation, an external feedback (Rf) and a serial resistor (Rd) are required. See Figure 28.

The POR time allows VDD and the oscillator circuit to stabilize before instruction execution begins. The POR timer circuit is a one-shot timer triggered by one of three conditions: * * * Power Fail to Power OK status, including Waking up from VBO Standby Stop-Mode Recovery (if D5 of SMR = 1) WDT Timeout The POR timer is 1 ms minimum. Bit 5 of the Stop-Mode Register determines whether the POR timer is bypassed after Stop-Mode Recovery (typical for external clock, RC and LC oscillators). Halt Mode This instruction turns off the internal CPU clock, but not the XTAL oscillation. The counter/timers and external interrupts IRQ0, IRQ1, IRQ2, IRQ3, IRQ4, and IRQ5 remain active. The devices are recovered by interrupts, either externally or internally generated. An interrupt request must be executed (enabled) to exit Halt Mode. After the interrupt service routine, the program continues from the instruction after the Halt. Stop Mode This instruction turns off the internal clock and external crystal oscillation, reducing the standby current to 10 A or less. Stop Mode is terminated only by a reset, such as WDT timeout, POR or SMR. This condition causes the processor to restart the application program at address 000Ch. In order to enter Stop (or Halt) mode, first flush the instruction pipeline to avoid suspending execution in midinstruction. Execute an NOP instruction (Opcode = FFh) immediately before the appropriate sleep instruction, as follows: PS021403-0304 P r e l i m i n a r y Functional Description CrimzonTM ZLR16300 Z8 Low-Voltage MCUs with Infrared Timers 48 FF 6F NOP STOP ; clear the pipeline ; enter Stop Mode FF 7F NOP HALT ; clear the pipeline ; enter Halt Mode or Port Configuration Register The Port Configuration (PCON) register (Figure 29) configures the comparator output on Port 3.

All bits are write only except bit 7, which is read only. Bit 7 is a flag bit that is hardware set on the condition of Stop recovery and reset by a power-on cycle. Bit 6 controls whether a low level or a high level at the XORgate input (Figure 32 on page 52) is required from the recovery source. Bit 5 controls the reset delay after recovery. Bits D2, D3, and D4 of the SMR register specify the source of the Stop-Mode Recovery signal. Bits D0 determines if SCLK/ TCLK are divided by 16 or not.

This condition allows the remaining inputs to control the AND/OR function. Refer to SMR2 register on page 54 for other recover sources. Stop Mode Recovery Delay Select (D5) This bit, if Low, disables the TPOR delay after Stop Mode Recovery. The default configuration of this bit is 1. If the "fast" wake up is selected, the Stop Mode Recovery source must be kept active for at least 5 TpC. Note: It is recommended that this bit be set to 1 if using a crystal or resonator clock source. The TPOR delay allows the clock source to stabilize before executing instructions. Stop Mode Recovery Edge Select (D6) A 1 in this bit position indicates that a High level on any one of the recovery sources wakes from Stop Mode. A 0 indicates Low level recovery. The default is 0 on POR. Cold or Warm Start (D7) This bit is read only. It is set to 1 when the device is recovered from Stop Mode. The bit is set to 0 when the device reset is other than Stop Mode Recovery (SMR).

Note: Port pins configured as outputs are ignored as an SMR or SMR2 recovery source. For example, if the NAND or P23-P20 is selected as the recovery source and P20 is configured as an output, the remaining SMR pins (P23-P21) form the NAND equation. PS021403-0304 P r e l i m i n a r y Functional Description CrimzonTM ZLR16300 Z8 Low-Voltage MCUs with Infrared Timers 55 Watch-Dog Timer Mode Register (WDTMR) The Watch-Dog Timer (WDT) is a retriggerable one-shot timer that resets the Z8(R) if it reaches its terminal count. The WDT must initially be enabled by executing the WDT instruction. On subsequent executions of the WDT instruction, the WDT is refreshed. The WDT circuit is driven by an on-board RC-oscillator. The WDT instruction affects the Zero (Z), Sign (S), and Overflow (V) flags. The POR clock source the internal RC-oscillator. Bits 0 and 1 of the WDT register control a tap circuit that determines the minimum timeout period. Bit 2 determines whether the WDT is active during HALT, and Bit 3 determines WDT activity during STOP. Bits 4 through 7 are reserved (Figure 34). This register is accessible only during the first 60 processor cycles (120 XTAL clocks) from the execution of the first instruction after Power-On-Reset, Watch-Dog Reset, or a Stop-Mode Recovery (Figure 33). After this point, the register cannot be modified by any means (intentional or otherwise). The WDTMR cannot be read. The register is located in Bank F of the Expanded Register File at address location 0Fh. It is organized as illustrated in Figure 34.

Because the XTAL clock is stopped during Stop Mode, the on-board RC has to be selected as the clock source to the WDT/POR counter. A 1 indicates active during Stop. The default is 1. ROM Selectable Options There are five ROM Selectable Options to choose from based on ROM code requirements. These options are listed in Table 19. Table 19.

Reset is globally driven when VDD falls below VBO. A small drop in VDD causes the XTAL1 and XTAL2 circuitry to stop the crystal or resonator clock. If the VDD is allowed to stay above VRAM, the RAM content is preserved. When the power level is returned to above VBO, the device performs a POR and functions normally.

Switching noise of both ports 0 and 1 together might trigger the LVD flag. Voltage Detection and Flags The Voltage Detection register (LVD, register 0Ch at the expanded register bank 0Dh) offers an option of monitoring the VCC voltage. The Voltage Detection is enabled when bit 0 of LVD register is set. When Voltage Detection is enabled, the the VCC level is monitored in real time. The flags in the LVD register valid 20uS after Voltage Detection is enabled. The HVD flag (bit 2 of the LVD register) is set only if VCC is lower than the VHVD. When Voltage Detection is enabled, the LVD flag also triggers IRQ5. The IRQ bit 5 latches the low voltage condition until it is cleared by instructions or reset. The IRQ5 interrupt is served if it is enabled in the IMR register. Otherwise, bit 5 of IRQ register is latched as a flag only. Note: Voltage Detection cannot be emulated with the emulator.
