CPU32 function code outputs are augmented by two supplementary signals to monitor
the instruction pipeline. The instruction pipe (IPIPE) output indicates the start of each
new instruction and each mid-instruction pipeline advance. The instruction fetch
(IFETCH) output identifies the bus cycles in which the operand is loaded into the in-
struction pipeline. Pipeline flushes are also signaled with IFETCH. Monitoring these
two signals allows a bus state analyzer to synchronize itself to the instruction stream
and monitor its activity.
An external breakpoint input and on-chip breakpoint hardware allow a breakpoint trap
on any memory access. Off-chip address comparators preclude breakpoints unless
show cycles are enabled. Breakpoints on instruction prefetches that are ultimately
flushed from the instruction pipeline are not acknowledged; operand breakpoints are
always acknowledged. Acknowledged breakpoints initiate exception processing at the
address in exception vector number 12, or alternately enter background mode.
