3.7 PowerPC UISA Register Set
MPC555
USER’S MANUAL
Where not otherwise noted, reserved fields in registers are ignored when written and
return zero when read. An exception to this rule is XER[16:23]. These bits are set to
the value written to them and return that value when read.
The PowerPC UISA registers can be accessed by either user- or supervisor-level in-
structions. The general-purpose registers are accessed through instruction operands.
