B/C: When B/C =0, a field AC waveform is generated. Alternation occurs every frame to drive liquid
crystal. When B/C=1, alternation occurs every n raster-rows according to the settings in EOR and NW5-0
bits of the LCD driving waveform control register. For details, see “n-raster-row Inversion AC Drive”.
EOR: When EOR = 1 and a C-pattern waveform is generated (B/C =1), an odd/even frame select signal
and an n-raster-row inversion signal are AC-driven. This instruction is available when liquid crystal AC
drive is not made depending on the combination of numbers of LCD drive raster-rows and the value of “n”
of n-raster-row inversion AC drive. For details, see “n-raster-row inversion AC drive”.
NW5-0: Specify n, the number of raster-rows from 1 to 64 to alternate every n+1 raster-rows when C-
pattern waveform is generated (B/C = 1).
