Figure 8-17. Stop Mode Recovery from Interrupt or Break
Address:
The SIM has two break registers and one reset register.
The break status register contains a flag to indicate that a break caused
an exit from stop or wait mode.
SBSW — SIM Break Stop/Wait
Reset:
Read:
Write:
This status bit is useful in applications requiring a return to wait or stop
mode after exiting from a break interrupt. Clear SBSW by writing a
logic 0 to it. Reset clears SBSW.
Note 1. Writing a logic 0 clears SBSW.
STOP +1
1 = Stop mode or wait mode was exited by break interrupt
0 = Stop mode or wait mode was not exited by break interrupt
