Note 1) A front porch period (set in the FP register) and a back porch period (set in the BP register) will be
inserted as a blank period before and after driving all gate lines.

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).
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”.
