Chapter 14 XGATE (S12XGATEV3)
14.2
The XGATE module has no external pins.
14.3
This section provides a detailed description of address space and registers used by the XGATE module.
The memory map for the XGATE module is given below in
is the sum of a 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. Reserved registers read zero. Write accesses to the reserved
registers have no effect.
14.3.1
This section consists of register descriptions in address order. Each description includes a standard register
diagram with an associated figure number. Details of register bits and field functions follow the register
diagrams, in bit order.
