Examples of settings for the instructions (reference examples)
Initial setting
Note:
After the power is switched ON, this LSI outputs at the LCD drive output pins SEG and
COM the V
SS
potential. If any charge is remaining on the smoothing capacitors
connected between the V
OUT
pin and the pins for the LCD drive voltage outputs (V1
to V5), there may be some abnormality in the display such as temporary blacking out
of the display screen when the power is switched ON.
The following procedure is recommended for avoiding such abnormalities at the time
the power is switched ON.
When using the internal power supply immediately after power-on

*(a):
Carry out power control set within 5ms after releasing the reset state.
The 5ms duration changes depending on the panel characteristics and the value of the
smoothing capacitor. We recommend verification of operation using an actual unit.
