15.4.4 Break Flag Control Register (BFCR)
The break control register contains a bit that enables software to clear status bits while the MCU is in a
break state.
BCFE — Break Clear Flag Enable Bit
15.5 Low-Power Modes
The WAIT and STOP instructions put the MCU in low-power-consumption standby modes.
15.5.1 Wait Mode
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 (see
zero to it.
15.5.2 Stop Mode
A break interrupt causes exit from stop mode and sets the SBSW bit in the break status register.

Freescale Semiconductor
This read/write bit enables software to clear status bits by accessing status registers while the MCU is
in a break state. To clear status bits during the break state, the BCFE bit must be set.
