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
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 (see
zero to it.
A break interrupt causes exit from stop mode and sets the SBSW bit in
the break status register. See
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.
