MC68H(R)C908JL3E/JK3E/JK1E
MOTOROLA
If a break module is present on the MCU, the CPU starts a break
interrupt by:
The break interrupt begins after completion of the CPU instruction in
progress. If the break address register match occurs on the last cycle of
a CPU instruction, the break interrupt begins immediately.
A return-from-interrupt instruction (RTI) in the break routine ends the
break interrupt and returns the MCU to normal operation if the break
interrupt has been deasserted.
