Datasheet
Section 6 PC Break Controller (PBC)
6.2.2
BARB is the channel B break address register. The bit configuration is the same as for BARA.
6.2.3
BCRA is an 8-bit readable/writable register that controls channel A PC breaks. BCRA (1) selects
the break condition bus master, (2) specifies bits subject to address comparison masking, and (3)
specifies whether the break condition is applied to an instruction fetch or a data access. It also
contains a condition match flag.
BCRA is initialized to H'00 by a reset and in hardware standby mode.
Bit 7—Condition Match Flag A (CMFA): Set to 1 when a break condition set for channel A is
satisfied. This flag is not cleared to 0.
