<GRAY1:0>.
<BULK>.
control palette is defined by 16-bit register (LGnL/H) shown in Table 3.14.5. Palette is
selected according to the gray scale level (Monochrome, 4, 8, 16 gray) for use. (Ref.
Table 3.14.6). On/off for data of each level (e.g., each density) can modify by 16-bit
register (LGnL/H). However each resister of palette has an initial value, it is possible
to adjust finely which matches to LCD driver you use and the characteristic of LCD
panel.

Monochrome, 4-, 8- and 16-gray scale mode can be selected by setting LCDGL
And when SDRAM mode, you can select the size of SDRAM by setting (LCDMODE)
TMP91C820A realize gray scale display by thinning out the frame. Gray scale
