NOTES:
2. WHEN STCPU = 1, THE CPU16L IS SHUT DOWN IN LPSTOP. ALL OTHER MODULES WILL REMAIN ACTIVE UNLESS
1. IMBCLK IS THE CLOCK USED BY THE CPU16L, SIML, ADC, MCCI, AND THE GPT.
3. THE SIMCLK IS USED BY THE PIT, IRQ, AND INPUT BLOCKS OF THE SIML.
4. CLKOUT CONTROL DURING LPSTOP IS OVERRIDDEN BY THE EXOFF BIT IN SIMCR. IF EXOFF = 1, THE CLKOUT
