IDPC. During a valid read transfer from IDPC data
simultaneously clocked out by the micro is ignored
by IDPC.
All data transfers through the microport are two-byte
transfers requiring the transmission of a Command/
Address byte followed by the data byte written or
read from the addressed register. CS must remain
asserted for the duration of this two-byte transfer. As
shown in Figures 5 and 6 the falling edge of CS
indicates to the IDPC that a microport transfer is
about to begin. The first 8 clock cycles of SCLK after
the falling edge of CS are always used to receive the
Command/Address byte from the microcontroller.
The Command/Address byte contains information
detailing whether the second byte transfer will be a
read or a write operation and at what address. The
next 8 clock cycles are used to transfer the data byte

Delays due to internal processor timing which are transparent to IDPC.
The IDPC:- latches received data on the rising edge of SCLK.
- outputs transmit data on the falling edge of SCLK.
y
The falling edge of CS indicates that a COMMAND/ADDRESS byte will be transmitted from the microprocessor. The
subsequent byte is always data until terminated via CS returning high.
A new COMMAND/ADDRESS byte may be loaded only byCS cycling high then low again.
The COMMAND/ADDRESS byte contains:
1 bit - Read/Write
5 bits - Addressing Data
2 bits - Unused
