5.7 SIM Registers
The SIM has three memory mapped registers.
5.7.1 Break Status Register (BSR)
The break status register contains a flag to indicate a break caused by an exit from wait mode.
SBSW — SIM Break Stop/Wait
Freescale Semiconductor
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.
INT/BREAK
