STOP: STOP Mode Select.
Writing a 1 to this bit will place the CIP-51 into STOP mode. This bit will always read 0.
1: CIP-51 forced into power-down mode. (Turns off internal oscillator).
IDLE: IDLE Mode Select.
Writing a 1 to this bit will place the CIP-51 into IDLE mode. This bit will always read 0.
1: CIP-51 forced into IDLE mode. (Shuts off clock to CPU, but clock to Timers, Interrupts,
and all peripherals remain active.)
