Section 6 PC Break Controller (PBC)
Notes: 1. Only a 0 can be written to this bit to clear the flag.
6.2.4
BCRB is the channel B break control register. The bit configuration is the same as for BCRA.
6.3
The operation flow from break condition setting to PC break interrupt exception handling is
shown in section 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. Set the break address in BARA.
2. Set the break conditions in BCR.
3. When the instruction at the set address is fetched, a PC break request is generated immediately
4. After priority determination by the interrupt controller, PC break interrupt exception handling

Bit
0
For a PC break caused by an instruction fetch, set the address of the first instruction byte as the
break address.
Set bit 6 (CDA) to 0 to select the CPU because the bus master must be the CPU for a PC break
caused by an instruction fetch. Set the address bits to be masked to bits 3 to 5 (BAMA2 to 0).
Set bits 1 and 2 (CSELA1 to 0) to 00 to specify an instruction fetch as the break condition. Set
bit 0 (BIEA) to 1 to enable break interrupts.

is started.
2. Read the state wherein CMFA = 1 twice or more, when the CMFA is polled after
