ISCT_SER
RCPU serialize control and
Instruction fetch show cycle
These bits control serialization and instruction fetch show
cycles. See
for the bit definitions.
NOTE: Changing the instruction show cycle programming
starts to take effect only from the second instruction after
the actual
mtspr
to ICTRL.
