Figure 10-16. Stop Mode Recovery from Interrupt or Break
The SIM has three memory mapped registers:
The SIM break status register (SBSR) contains a flag to indicate that a break
caused an exit from stop or wait mode.
SBSW — SIM Break Stop/Wait Bit

Address:
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. Writing 0 to the SBSW
bit clears it.
Reset:

Write:
1 = Wait mode was exited by break interrupt.
0 = Wait mode was not exited by break interrupt.
