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. (Refer to
the Standby Mode section.)

Driver Output Control
CMS:
Selects the output shift direction of a common driver. When CMS = "0", COM1/24 shifts to COM1,
and COM24/1 to COM24. When CMS = "1", COM1/24 shifts to COM24, and COM24/1 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", SEG1/72 (96) shifts to
SEG1, and SEG72 (96)/1 to SEG72 (96). When SGS = "1", SEG1/72 (96) shifts SEG72 (96), and SEG72
(96)/1 to SEG1.

Power Control
AMP:
When AMP = 1, each voltage follower for the V1 to V5 pins and the booster are turned on. When
AMP = 0, current consumption can be reduced when the display is not being used. In this case, set BT1/0
= 00 for single boosting output.
SLP:
When SLP = 1, the HD66724/HD66725 enter 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, refer to 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)
