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.
7.7 SIM Registers
The SIM has three memory-mapped registers:

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