Registers D-11

EXC_ADDR[0] is set if the associated exception occurred in PAL mode. The

exception actions are:

•

If the exception was a fault or a synchronous trap, EXC_ADDR contains the

PC of the instruction that triggered the fault or trap.

•

If the exception was an interrupt, EXC_ADDR contains the PC of the next

instruction that would have executed if the interrupt had not occurred.
