Base image control instructions
NL0[5:0]: Set the number of liquid crystal drive raster-rows. The number of raster-rows can be set to 8
multiples. The GRAM address mapping is made irrespective of the value set for the number of raster-rows
to drive liquid crystal. The value should be set equal to or more than to drive the number of raster-rows
required for the panel size.
REV: When REV = 1, a reverse display is shown within the display area. The grayscale level inversion
enables to use same data to display on both normally white and normally black panels. The REV setting is
effective for both OSD and base image areas.
The source outputs during front and back porches and a blank period during partial display mode depend on
the setting of PTS bits.
