2.3 DSP CLOCK
The DSP clock is derived from the 8.192Mhz oscillator Y4. A voltage level converter is used
because the DSP’s EXTAL requires 3.3V operation. The PINIT signal is tied low, which
disables the PLL when it resets. Because of this, the PLL’s multiplication factor must be
configured in user software. If the multiplication factor is not set, the DSP operating clock is
4.096Mhz (half of 8.192Mhz). Refer to Figure 2-15 for more information.
2.4 HOST MICROCONTROLLER INTERFACE
The MC68HC711E20 microcontroller communicates with the DSP using the Serial Host
Interface (SHI) port in SPI mode. When SS is pulled low by the microcontroller, the
microcontroller can write to the DSP. The MOSI and MISO lines pass control data through
the DSP SHI in 24-bit mode. SCK is the SPI Shift Clock from the DSP.
The microcontroller also receives commands from the momentary push-button switches S2,
S3, S4, or S5. The results of these commands are then displayed by a modular LCD panel wit h
a 2 x 20 line character display. These commands control the settings of the executed software.
The microcontroller also receives status information from the DSP.

2.6 PLD FUNCTIONS
The PLD performs the following functions:
• Determines if S/PDIF or analog input is present.
• Performs clock division.
• Generates the DSP clock.
• Selects DACs for initialization.
• Inverts RESET signal for the HC08 microcontroller.
The PLD determines if the input to the DSP comes from the S/PDIF receiver or the A/D
converter. If JP20 is jumpered (JUMP = logic 0) the PLD is notified that the input is from the
S/PDIF receiver. In this case, the system clock, left/right clock, and bit clock that are
generated by the S/PDIF receiver, are passed through the PLD as shown in Figure 2-13.
Figure 2-13 PLD Clock Outputs - S/PDIF
If JP20 is not jumpered (JUMP = logic 1) then the PLD assumes that the input is from the A/D
converter. In this case, the system clock, left/right clock, and bit clock are generated from
oscillators depending on the selected sampling rate on JP24. Figure 2-14 shows these
sampling rates.

The SRAM can be upgraded up to 512k x 24-bits. When using 512k x 24-bits of SRAM, the
upper half of memory is accessible by controlling the address attribute line AA0. AA0 is
connected to the memory’s most significant address line.
2.10.2 EPROM
The Evaluation Module has 128k x 8-bits of EPROM. To keep the address stable during the
entire bus cycle, insert a minimum of 1 wait state to the bus operation.
Select the EPROM by configuring the DSP’s address attribute register to assert the AA1 line.
2.10.3 EXTERNAL MEMORY BLOCK DIAGRAM
The following figure shows the functional block diagram of the external memory
interface.Memory data is accessible through the JP13-JP15 headers.

2.11 POWER SUPPLY
The Evaluation Module requires an input voltage of 7.5-9V AC/DC (recommended 1A) for
both analog and digital circuits. It has separate digital and analog power and ground planes
and voltage regulators to output the +5V, +5VA and +3.3V supplies. The DC-DC converter
outputs the -5V supply. When power is supplied to the 2.1mm power connector P2 or to the
2-pin terminal block P3, the green LED D8 is powered on. The polarity of the voltage applied
to the P3 terminal block is reversible because the power goes through a bridge rectifier.
Note: While the voltage regulators can accommodate higher input voltage potentials, the
added heat dissipation required at these input voltage levels results in the regulator
becoming dangerously warm. It is recommended that users do not subject the
board to power inputs in excess of the 12V.

MOTOROLA DSP56362EVM User’s Manual 6-1
SECTION 6
RUNNING THE PASS-THROUGH CODE
The Evaluation Module includes an HC11 with the pass-through files programmed in the
EPROM. The pass-through software allows users to input and output audio to the Evaluation
Module without loading the files through the OnCE (stand-alone mode).
6.1 PASS-THROUGH OPERATION
The main loop of the digital.asm and analog.asm programs serve as a reference guide
on how to pass data into and out of the EVM.
6.1.1 RECEIVE INTERRUPT SERVICE ROUTINES
The receive interrupt service routine esai_rx_isr moves the left data word from the receive
data register RXn (RX0 or RX1) into the receive left data buffer RX_BUFF_BASE and
moves the right da ta word from the receive da ta register RXn int o the re ceive ri ght data buffer
RX_BUFF_BASE+1. The pointer to the RX_BUFF_BASE has modulo of 2, so it alternates
between the left and right receive buffers.
If the serial receive shift register SDI0 or SDI1 is filled and ready to transfer to the receiver
data register RXn and RXn is already filled, then the Receiver Overrun Error Flag (ROE) is
set and the receive with exception interrupt service routine esai_rxe_isr is called. This routine
clears the ROE bit.
The receive last slot interrupt service routine esai_rxls_isr resets the buffer pointer to
RX_BUFF_BASE in case the pointer is corrupted after the last slot of the frame. For example,
after the right data is received.

6.1.2 TRANSMIT INTERRUPT SERVICE ROUTINES
The transmit interrupt service routine moves the left data word from the transmit left data
buffer TX_BUFF_BASEinto the transmit data register TXn (TX0, TX1, TX2 or TX3) and
moves the right data word from the transmit right data buffer TX_BUFF_BASE+1 into the
transmit data register TXn. The pointer to the TX_BUFF_BASE has modulo of 2 so it
alternates between left and right transmit buffers.
If the serial receive shift register SDI0 or SDI1 is filled and ready to transfer to the receiver
data register RXn and RXn is already filled, then the Receiver Overrun Error Flag (ROE) is
set and the receive with exception interrupt service routine esai_rxe_isr is called. This routine

6.1.3 MAIN LOOP
Bit 6 of the ESAI Status Register (SAISR) which is the receive frame sync flag (RFS) is
polled to wait for a frame sync to occur. When the frame sync occurs, the contents of the input
buffers RX_BUFF_BASE and RX_BUFF_BASE+1 are copied to accumulators a and b.
Users can insert additional processing code at this point. If no processing is required, the
contents of accumulators a and b are copied to the output buffers TX_BUFF_BASE and
TX_BUFF_BASE+1. The program jumps back to the beginning of the loop for the next
sample.
