Break (BRK)
20.6.3 SIM Break Status Register
Technical Data
336
The SIM break status register (SBSR) contains a flag to indicate that a
break caused an exit from wait mode. The flag is useful in applications
requiring a return to wait mode after exiting from a break interrupt.
Reset:
BW — Break Wait Bit
BW can be read within the break interrupt routine. The user can modify
the return address on the stack by subtracting 1 from it. The example
code shown in
break interrupt routine. Execute this code at the end of the break
interrupt routine.

Write:
Ad-
This read/write bit is set when a break interrupt causes an exit from
wait mode. Clear BW by writing a logic 0 to it. Reset clears BW.
Note: Writing a logic 0
1 = Break interrupt during wait mode
0 = No break interrupt during wait mode
