11.13.8 PPC Register Locations
Table 11-21 shows 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.
