Section 6 PC Break Controller (PBC)
Bit 0—Break Interrupt Enable A (BIEA): Enables or disables channel A PC break interrupts.

Bit
Initial value
Read/Write
MSTPCRC is an 8-bit readable/writable register that performs module stop mode control.
When the MSTPC4 bit is set to 1, PC break controller operation is stopped at the end of the bus
cycle, and module stop mode is entered. Register read/write accesses are not possible in module
stop mode. For details, see section 22.5, Module Stop Mode.
MSTPCRC is initialized to H'FF by a reset and in hardware standby mode. It is not initialized in
software standby mode.
Bit 4—Module Stop (MSTPC4): Specifies the PC break controller module stop mode.
