- Sleep Mode
This stops all operations in the LCD display system, and as long as there are no access from the MPU, the
consumption current is reduced to a value near the static current. The internal modes during sleep mode are
as follows:
a. The oscillator circuit and the LCD power supply circuit are halted.
b. All liquid crystal drive circuits are halted, and the segment in common drive outputs output a VSS level.
- Standby Mode
The duty LCD display system operations are halted and only the static drive system for the indicator
continues to operate, providing the minimum required consumption current for the static drive.
The internal modes are in the following states during standby mode.
a. The LCD power supply circuits are halted. The oscillator circuit continues to operate.
b. The duty drive system liquid crystal drive circuits are halted and the segment and common driver outputs
a VSS level. The static drive system does not operate.
When a reset command is performed while in standby mode, the system enters sleep mode.
