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.
14.7 SIM Registers
The SIM has three memory-mapped registers.

CGMXCLK
INT/BREAK
IAB
To minimize stop current, all pins configured as inputs should be driven to
a logic 1 or logic 0.
