NOTE:
Figure 9-19. Stop Mode Recovery from Interrupt or Break
A break interrupt during stop mode sets the SIM break stop/wait bit
(SBSW) in the SIM break status register (SBSR).
The SIM counter is held in reset from the execution of the STOP
instruction until the beginning of stop recovery. It is then used to time the
recovery period.
To minimize stop current, all pins configured as inputs should be driven
to a logic 1 or logic 0.
The SIM has three memory-mapped registers:
