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.
15-20
15.7 SIM Registers
The SIM has three memory-mapped registers.

shows stop mode recovery time from interrupt.
CGMXCLK
INT/BREAK
IAB
To minimize stop current, all pins configured as inputs should be driven to
a 1 or 0.
Note: Previous data can be operand data or the STOP opcode, depending on the last instruction.
