Field Bits Type Description
BER 0rhBus Error Flag
Set if the last error/debug event was an error
generated by an FPI Bus error or an invalid address
access; otherwise, clear.
Note: An FPI Bus error event does not cause the PCP
to post an error interrupt to the CPU. An FPI Bus
error interrupt is, however, generated by the FPI
control logic.
IOP 1rhInvalid Opcode
Set if the last error/debug event was an error
generated by the PCP attempting to execute an Invalid
Opcode (i.e. the value fetched from CMEM for
execution by the PCP did not represent a valid
instruction), otherwise clear.
DCR 2rhDisabled Channel Request Flag
Set if the last error/debug event was an error
generated by receipt of an interrupt request with an
SRPN that attempted to start a disabled PCP channel;
otherwise, clear.
