6.3
The operation flow from break condition setting to PC break interrupt exception handling is
shown in sections 6.3.1, PC Break Interrupt Due to Instruction Fetch and 6.3.2, PC Break Interrupt
Due to Data Access, taking the example of channel A.
6.3.1
(1) Initial settings
(2) Satisfaction of break condition
(3) Interrupt handling
Set the break address in BARA. For a PC break caused by an instruction fetch, set the
address of the first instruction byte as the break address.
Set the break conditions in BCRA.
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 5–3 (BAMA2–0): Set the address bits to be masked.
BCRA bits 2, 1 (CSELA1, 0): Set 00 to specify an instruction fetch as the break condition.
BCRA bit 0 (BIEA): Set to 1 to enable break interrupts.
When the instruction at the set address is fetched, a PC break request is generated
immediately before execution of the fetched instruction, and the condition match flag
(CMFA) is set.
After priority determination by the interrupt controller, PC break interrupt exception
handling is started.
