Serial Peripheral Interface (S12SPIV5)
21.1
The SPI module allows a duplex, synchronous, serial communication between the MCU and peripheral
devices. Software can poll the SPI status flags or the SPI operation can be interrupt driven.
21.1.1
21.1.2
The SPI includes these distinctive features:
21.1.3
The SPI functions in three modes: run, wait, and stop.
