Sleep Mode
Setting the sleep mode bit (SLP) to 1 puts the HD66724/HD66725 in the sleep mode, where the device
stops all internal display operations except for key scan operations, thus reducing current consumption.
Specifically, LCD drive is completely halted. Here, all the SEG (SEG1 to SEG72 (96)) and COM (COM1
to COM24, COMS1/2) pins output the GND level, resulting in no display. If the AMP bit is set to 0 in the
sleep mode, the LCD drive power supply can be turned off, reducing the total current consumption of the
LCD module.
The key scan circuit operates normally in the sleep mode, thus allowing normal key scan and key scan
interrupt generation. For details, refer to the Key Scan Control section and Key Scan Interrupt (Wake-up
Function) section.
