• Manufacturer Part Number: mm912f634
• Description: Mm912f634 - Integrated S12 Based Relay Driver With Lin
• Manufacturer: Freescale Semiconductor, Inc

Functional Description and Application Information
4.38.2.3
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.
4.38.2.4
In master mode, this is the synchronous output clock. In slave mode, this is the synchronous input clock.
4.38.3
This section provides a detailed description of address space and registers used by the SPI.
4.38.3.1
The memory map for the S12SPIV4 is given in
Table 400. SPI Register Summary
4.38.3.2
This section consists of register descriptions in address order. Each description includes a standard register diagram with an
associated figure number. Details of register bit and field function follow the register diagrams, in bit order.
