Sleep Mode
Setting the sleep mode bit (SLP) to 1 puts the HD66717 in sleep mode, where the device halts all the
internal display operations except for annunciator display operations, thus reducing current consumption.
Specifically, character and segment displays, which are controlled by the multiplexing drive method, are
completely halted. Here, all the SEG (SEG1 to SEG60) and COM (COM1 to COM34) pins output the V
CC
level, resulting in no display. If the AMP bit is set to 0 in sleep mode, the LCD drive power supply can be
turned off, reducing the total current consumption of the LCD module.
Annunciators can be normally displayed in sleep mode. Since they are driven at logic operating power
supply voltage (V
CC
– AGND), they are available even if the LCD power supply is turned off (AMP = 0).
This function allows time and alarm marker indication during system standby with reduced current
consumption.
During sleep mode, no instructions can be accepted for character/segment display and neither DDRAM,
CGRAM, nor SEGRAM can be accessed.
Table 27 compares the functions of sleep mode and standby mode.
