The following conventions are used in the Hawk register charts:
R - Read Only field.
R/W - Read/Write field.
S - Writing a ONE to this field sets this field.
C - Writing a ONE to this field clears this field.
The MPIC register map is shown in
address offset from the base address of the MPIC registers in the PPC-IO
or PPC-Memory space. Note that this map does not depict linear
addressing. The PCI-SLAVE of the PHB has two decoders for generating
the MPIC select. These decoders will generate a select and acknowledge
all accesses which are in a reserved 256K byte range. If the index into that
256K block does not decode a valid MPIC register address, the logic will
return $00000000.
The registers are 8, 16, or 32 bits accessible.
