11.13.8PPC Register Locations

Table 11-21shows the registers associated with the PPC and the physical addresses used to access them. Note that serial port 2 (ICP) has implemented HSSP control register 2 and serial port 4 (MCP) has also implemented MCP control register 1 within the PPC’s address space at 0h 9006 0028 and 0h 9006 0030 respectively. The user should ensure that these registers are not accidentally written by any PPC routines that may attempt to write to all of the PPC’s address space, including its reserved registers during initialization.
