16.2.2.3 Break Auxiliary Register
The break auxiliary register (BRKAR) contains a bit that enables software to disable the COP while the
MCU is in a state of break interrupt with monitor mode.
BDCOP — Break Disable COP Bit
16.2.2.4 Break Status Register
The break status register (BSR) contains a flag to indicate that a break caused an exit from wait mode.
This register is only used in emulation mode.
SBSW — SIM Break Stop/Wait
16.2.2.5 Break Flag Control Register
The break control register (BFCR) 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
This read/write bit disables the COP during a break interrupt. Reset clears the BDCOP bit.
SBSW can be read within the break state SWI routine. The user can modify the return address on the
stack by subtracting one from it.
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 = COP disabled during break interrupt
0 = COP enabled during break interrupt
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
