CH5-CH0 - Defines the character vertical height. The height is programmable from 16 to 63 lines.
The character vertical height is at least 16 lines if the contents of CH5-CH0 are less than 16. For example,
when CH5~CH0 contents equal 2, the character vertical height is regarded as equal to 18 lines. See Tables 2
and 3 for a detailed description of this operation.

OSDEN
BSEN

FBKGC
OSDEN - Activates OSD operation when this bit is set to 1.
BSEN - Enables the bordering and shadowing effect.
SHADOW - Activates the shadowing effect if this bit is set, otherwise the bordering is chosen.
FBKGC - Defines the output configuration for the FBKG pin. When it is set to 0, the FBKG outputs High during
the display of characters or windows, otherwise it outputs High only during the display of characters.
3.10 Color Encoder
The decoder generates video output to ROUT, GOUT and BOUT by integrating window color, border blacking,
luminance output and color selection output (CCS0, CCS1) to form desired video outputs.
