Sleep Mode
This stops all operations in the LCD display system, and as long as there are no
accesses from the MPU, the consumption current is reduced to a value near the static
current. The internal modes during sleep mode are as follows:
1.
The oscillator circuit and the LCD power supply circuit are stopped.
2.
All liquid crystal drive circuits are stopped, and the segment and common driver
output VSS level.
When a “static indicator on” instruction is issued in the sleep mode, the LSI goes into the
standby mode.
Standby Mode
All operations of the dynamic LCD display section are stopped, only the static display
circuits for the indicators operate and hence the current consumption will be the
minimum necessary for static drive. The internal conditions in the standby state are as
follows:
1.
The power supply circuit for LCD drive is stopped. The oscillator circuit will be
operating.
2.
The LCD drive circuits for dynamic display are stopped and the segment and
common driver outputs will be at the VSS level. The static display section will be
operating.
When a reset instruction is issued in the standby mode, the LSI goes into the sleep
mode.
