LCD Driving Wave (R3)
B/C:
Specifies the LCD alternating method. When B/C = "0", a B-pattern waveform is generated and
alternates in every frame. When B/C = "1", a C-pattern waveform is generated and alternates (n-raster-row
reversed AC drive) in each raster-row specified by NW4–NW0. For details, see the n-raster-row Reversed
AC Drive section.
EOR:
When the C-pattern waveform is set and EOR = "1", the odd/even frame-select signals and the n-
raster-row reversed signals are EORed for alternating drive. EOR is used when the LCD is not alternated
by combining the set values of the LCD drive duty ratio and n raster-row.
NW4–0:
Specify the number of raster-rows n that will alternate at the C-pattern waveform setting. NW4–
NW0 alternate in every n + 1 raster-row, and the first to the 32nd raster-row can be selected.

LCD Driving Control (R4)
BS2–0:
Set the LCD drive bias values in the range of 1/2 to 1/8 bias. The LCD drive bias value can be
selected according to the LCD drive duty and LCD drive voltage. For details, see the LCD Drive Bias
Selector section.
CT4–CT0:
Control the LCD drive voltage (potential difference between V1 and GND) to adjust contrast.
A 32-step adjustment is possible. For details, see the Contrast Adjuster section.
