Chapter 13 Serial Communications Interface (S12SCIV2) Block Description
13.3
This section provides a detailed description of all memory and registers.
13.3.1
The memory map for the SCI module is given below in
is the address offset. The total address for each register is the sum of the base address for the SCI module
and the address offset for each register.
13.3.2
This section consists of register descriptions in address order. Each description includes a standard register
diagram with an associated figure number. Writes to a reserved register location do not have any effect and
reads of these locations return a zero. Details of register bit and field function follow the register diagrams,
in bit order.
