System Integration Module (SIM)
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.

shows the stop mode recovery time from interrupt or break.
To minimize stop current, all pins configured as inputs should be driven to
a logic 1 or logic 0.
