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.

13.8 SIM Registers
The SIM has three memory mapped registers.

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