Chapter 21 Serial Peripheral Interface (S12SPIV5)
21.2.3
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.
21.2.4
In master mode, this is the synchronous output clock. In slave mode, this is the synchronous input clock.
21.3
This section provides a detailed description of address space and registers used by the SPI.
21.3.1
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
no effect.
