Enabling data retry mode
The PowerPC 603 processor can be powered on with data retry mode
enabled or not depending on the state of the DRTRY processor pin. This
cannot be detected by the HP processor probe. This mode is only used when
the cache is enabled. If either the instruction and/or data cache is enabled,
this configuration item must match the state of the processor as determined
by the DRTRY pin on powerup. If the cache is disabled, this setting has no
effect. The debug mode of the PowerPC 603e does not require different
actions based on the DRTRY mode, so this configuration item does not exist
for the 603e.
cf drtry=off
Disable the data retry mode of the PowerPC 603
cf drtry=on
Enable the data retry mode of the PowerPC 603
N o t e
The drtry setting must be set correctly if either cache is used. Failure to do
so will cause incorrect data to be displayed or written and possibly
communication problems between the processor probe and the target
system.
Default: drtry=off
