Start Oscillation
The start oscillation instruction restarts the oscillator from the halt state in the standby mode. After issuing
this instruction, wait at least 10 ms for oscillation to stabilize before issuing the next instruction. (See the
Standby Mode section.)

Driver Output Control
CMS:
Selects the output shift direction of a common driver. When CMS = "0", COM1/80 shifts to COM1,
and COM80/1 to COM80. When CMS = "1", COM1/80 shifts to COM80, and COM80/1 to COM1.
Output position of a common driver shifts depending on the CN1–0 bit setting. For details, see the Display
On/Off Control section.
SGS:
Selects the output shift direction of a segment driver. When SGS = "0", SEG1/112 shifts to SEG1,
and SEG112/1 to SEG112. When SGS = "1", SEG1/112 shifts SEG112, and SEG112/1 to SEG1.
