Serial Peripheral Interface (S08SPIV3)
13.1
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 in master mode and up to the bus clock
divided by four in slave mode. Software can poll the status flags, or SPI operation can be interrupt driven.
All MC9S08DZ128 Series MCUs in the 100-pin package have two SPIs; devices in the 64-pin and 48-pin
packages have one SPI.
