Serial Peripheral Interface (S08SPIV3)
11.1
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 bus clock divided by
four in slave mode.
All devices in the MC9S08EN32 Series MCUs contain one SPI module, as shown in the following block
diagram.

Introduction
Ensure that the SPI should not be disabled (SPE=0) at the same time as a bit
change to the CPHA bit. These changes should be performed as separate
operations or unexpected behavior may occur.
