Chapter 21 Serial Peripheral Interface (S12SPIV5)

This pin is used to output the select signal from the SPI module to another peripheral with which a data

transfer is to take place when it is conﬁgured as a master and it is used as an input to receive the slave select

signal when the SPI is conﬁgured as slave.

In master mode, this is the synchronous output clock. In slave mode, this is the synchronous input clock.

This section provides a detailed description of address space and registers used by the SPI.

The memory map for the SPI is given in

base address and an address offset. The base address is deﬁned at the SoC level and the address offset is

deﬁned at the module level. Reads from the reserved bits return zeros and writes to the reserved bits have
