17.2 Introduction
The serial peripheral interface (SPI) module allows full-duplex,
synchronous, serial communication between the microcontroller unit
(MCU) and peripheral devices. Software can poll the SPI status flags or
SPI operation can be interrupt driven.
17.3 Features
Features include:
⢠Master mode and slave mode
⢠Wired-OR mode
⢠Slave-select output
⢠Mode fault error flag with central processor unit (CPU) interrupt
capability
⢠Double-buffered operation
⢠Serial clock with programmable polarity and phase
⢠Control of SPI operation during doze mode
⢠Reduced drive control for lower power consumption
