SBSW — Break Wait Bit
21.5.4 SIM Break Flag Control Register
The SIM break flag control register (SBFCR) contains a bit that enables software to clear status bits while
the MCU is in a break state.
BCFE — Break Clear Flag Enable Bit
Freescale Semiconductor
SBSW can be read within the break interrupt routine. The user can modify the return address on the
stack by subtracting 1 from it. The following code is an example.
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.
1 = Wait mode was exited by break interrupt
0 = Wait mode was not exited by break interrupt
1 = Status bits clearable during break
0 = Status bits not clearable during break
