System Integration Module (SIM)
15.7 SIM Registers
The SIM has three memory-mapped registers.
15.7.1 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
192
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.
1 = Wait mode was exited by break interrupt.
0 = Wait mode was not exited by break interrupt.
