Figure 11 Cursor Control Examples
Display On/Off Control
The display on/off control instruction (Figure 12) includes the D, FW, and LC bits.
D:
The character display and the segment display for multiplexing icon are on when D is 1. When off, the
display data remains in DDRAM or SEGRAM, and can be displayed instantly by setting D to 1. When D is
0, multiplexing LCD drive halts and the display is off with the SEG1 to SEG60 outputs, COM1 to COM32
outputs, and COMS1/2 output set to V
CC
level and off. Because of this, the HD66727 can control charging
current for the LCD with driving.
FW:
When FW = 0, the font width is 5 dots. When FW = 1, the font width is 6 dots.
LC:
When LC = 1, a cursor attribute is assigned to the line that contains the address counter (AC) value.
Cursor mode can be selected with the B/W, C, and B bits. Refer to the Line-Cursor Display section.

Figure 12 Display On/Off Control Instruction
Power Control
The power control instruction (Figure 13) includes the AMP, SLP, and STB bits.
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 character or segment display controlled by the multiplexing
drive method is not being used.
SLP:
When SLP = 1, the HD66727 enters the sleep mode, where all the internal operations are halted
except for the annunciator display function, key scan function, and the R-C oscillator, thus reducing current
