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", COM1/40 shifts to COM1,
and COM40/1 to COM40. When CMS = "1", COM1/40 shifts to COM40, and COM40/1 to COM1.
Output position of a common driver shifts depending on the CEN bit setting. For details, see the Display
On/Off Control section.
SGS:
Selects the output shift direction of a segment driver. When SGS = "0", SEG1/96 shifts to SEG1,
and SEG96/1 to SEG96. When SGS = "1", SEG1/96 shifts SEG96, and SEG96/1 to SEG1.

Power Control
AMP:
When AMP = 1, each voltage follower for V1 to V5 pins and the booster are turned on. When AMP
= 0, current consumption can be reduced while the display is not being used.
SLP:
When SLP = 1, the HD66726 enters the sleep mode, where the internal operations are halted except
for the key scan function and the R-C oscillator, thus reducing current consumption. For details, see the
Sleep Mode section. Only the following instructions can be executed during the sleep mode.
a. Key scan data read
b. Key scan control (IRE, KF1/0 bit)
c. Power control (AMP, SLP, and STB bits)
d. Port control (PT2-0 bits)
During the sleep mode, the other RAM data and instructions cannot be updated although they are retained.
STB:
When STB = 1, the HD66726 enters the standby mode, where display operation and key scan
completely stops, halting all the internal operations including the internal R-C oscillator. Further, no
