Serial Peripheral Interface (S08SPIV3)
15.1
Introduction
The serial peripheral interface (SPI) module provides for full-duplex, synchronous, serial communication
between the MCU and peripheral devices. These peripheral devices can include other microcontrollers,
analog-to-digital converters, shift registers, sensors, memories, etc.
The SPI runs at a baud rate up to the bus clock divided by two. Software can poll the status flags, or SPI
operation can be interrupt driven.
