Break Module (BREAK)
15.4.2 Break Address Registers
The break address registers contain the high and low bytes of the desired breakpoint address. Reset
clears the break address registers.
15.4.3 Break Status Register
The break status register contains a flag to indicate that a break caused an exit from wait mode.
SBSW — SIM Break Stop/Wait
132
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
