8.4
The MC1323x has one serial peripheral interface module. The SPI is a synchronous serial data
input/output port used for interfacing with serial memories, peripheral devices, or other processors. The
SPI allows an 8-bit serial bit stream to be shifted simultaneously into and out of the device at a
programmed bit-transfer rate (called 4-wire mode). There are four pins associated with the SPI port
(SPCLK, MOSI, MISO, and SS).
The SPI module can be programmed for master or slave operation. It also supports a 3-wire mode where
for master mode the MOSI becomes MOMI, a bidirectional data pin, and for slave mode the MISO
becomes SISO, a bidirectional data pin. In 3-wire mode, data is only transferred in one direction at a time.
The SPI bit clock is derived from the peripheral input clock with a maximum 16 MHz operation. A
programmable prescaler (maximum divide-by-8) drives a second baud rate programmable divider
(maximum divide-by-256) to develop the bit clock. The maximum SPI transfer rate is 8 MHz.
Features of SPI module include:

The MC1323x has one inter-integrated circuit interface module that provides a method of communication
between a number of other integrated circuits. The IIC Bus interface provides a bidirectional, 2-pin (SDA
bus data and SCL bus clock) serial bus designed to operate up to 100 kbps with maximum bus loading and
timing. The module is capable of operating at higher baud rates, up to a maximum of peripheral clock/20
(800 kbps), with reduced bus loading.
