When the processor is inthe trace mode and attempts to execute an illegal

The exception processing for a trace starts at the end of normal processing
for the traced instruction and before the start of the next instruction. The
trace exception and saves the trace exception vector offset, program counter
value, and the copy of the status register on the supervisor stack. The saved
value of the program counter is the logical address of the next instruction
to be executed. Instruction execution resumes after the required prefetches
from the address in the trace exception vector.
In general terms, a trace exception is an extension to the function of any
plete until the trace exception processing is completed: If an instruction does
not complete due to a bus error or address error exception, trace exception
processing is deferred until after the execution of the suspended instruction
is resumed and the instruction execution completes normally. If an interrupt
is pending at the completion of an instruction, the trace exception processing
an exception as part of its normal execution, the forced exception processing
occurs before the trace exception is processed. See 8.1.12 Multiple Excep-
or unimplemented instruction, that instruction does not cause a trace ex-
ception since it is not executed. This is of particular importance to an instruc-
stacked program counter to skip the unimplemented instruction, and returns.
