Notes for Low Current Consumption

The S1C6S3N2 Series contains control registers for each of
the circuits so that current consumption can be lowered.
These control registers lower the current consumption
through programs that operate the circuits at the minimum
levels.
The following text explains the circuits that can control
operation and their control registers. Refer to these when
putting programs together.
Circuits (and Items)
Below are the circuit statuses at initial reset.

Also, be careful about panel selection because the current
consumption can differ by the order of several µA on ac-
count of the LCD panel characteristics.
