Serial Peripheral Interface (S08SPIV3)
13.1
The serial peripheral interface (SPI) module provides 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, and so forth.
The maximum SPI baud rate depends on the operating mode:
The SPI operation can be driven by interrupts or software can poll the status flags.
All devices in the MC9S08EL32 Series and MC9S08SL16 Series MCUs contain one SPI module
