Break Module Registers

MOTOROLA
The WAIT and STOP instructions put the MCU in low-power-consump-
tion standby modes.
If enabled, the break module is active in wait mode. A DMA-generated
address that matches the break address registers in wait mode sets the
BW in the break status register.
The DMA can also use the break status and control register as its
destination address in order to write to the BRKA and BRKE bits during
wait mode. A DMA write to the break status and control register sets the
BW bit.
The break module is inactive in stop mode. The STOP instruction does
not affect break module register states.
These registers control and monitor operation of the break module:
