20.6 Break Module Registers
20.6.1 Break Status and Control Register

Freescale Semiconductor
The WAIT and STOP instructions put the MCU in low power-
consumption standby modes.
If enabled, the break module is active in wait mode. In the break routine,
the user can subtract one from the return address on the stack if SBSW
is set. Clear the BW bit by writing logic 0 to it.
A break interrupt causes exit from stop mode and sets the SBSW bit in
the break status register.
These registers control and monitor operation of the break module:
The break status and control register (BRKSCR) contains break module
enable and status bits.
