If enabled, the Missing Clock Detector will cause an internal reset and thereby terminate the Stop mode. The
Missing Clock Detector should be disabled if the CPU is to be put to sleep for longer than the MCD timeout of
100
sec.

Bit7:
SMOD: Serial Port Baud Rate Doubler Enable.
0: Serial Port baud rate is that defined by Serial Port Mode in SCON.
1: Serial Port baud rate is double that defined by Serial Port Mode in SCON.
Bits6-2: GF4-GF0: General Purpose Flags 4-0.
These are general purpose flags for use under software control.
Bit1:
STOP: Stop Mode Select.
Setting this bit will place the CIP-51 in Stop mode. This bit will always be read as 0.
1: Goes into power down mode. (Turns off internal oscillator).
Bit0:
IDLE: Idle Mode Select.
Setting this bit will place the CIP-51 in Idle mode. This bit will always be read as 0.
1: Goes into idle mode. (Shuts off clock to CPU, but clock to Timers, Interrupts, Serial
Ports, and Analog Peripherals are still active.)
