⎯ Set the break address in BARA. For a PC break caused by an instruction fetch, set the
⎯ Set the break conditions in BCRA.
⎯ When the instruction at the set address is fetched, a PC break request is generated
⎯ After priority determination by the interrupt controller, PC break interrupt exception
address of the first instruction byte as the break address.
BCRA bit 6 (CDA): With a PC break caused by an instruction fetch, the bus master must
be the CPU. Set 0 to select the CPU.
BCRA bits 5 to 3 (BAMA2 to BAMA0): Set the address bits to be masked.
BCRA bits 2, 1 (CSELA1, CSELA0): Set 00 to specify an instruction fetch as the break
condition.
BCRA bit 0 (BIEA): Set to 1 to enable break interrupts.
