A logical 1 TP6508 selects 8 bits color STN interface
A logical 1 TP6508 switches the panel display timing to enhance color STN timing.
A logical 1 TP6508 selects CRT-like LP(Hsync) and FLM(Vsync) for TFT LCD panel.
A logical 1 disables the CRT display , and a logical 0 enables it.
A logical 1 enables the flat panel display, and a logical 0 disables the flat panel display.
A logical 1 TP6508 selects 8 bits PLASMA interface . And a logical 0 TP6508 selects 4 bits PLASMA
interface.
This bit is use to set the gray conversion type for mono flat panel display . A logical 1 enable it , a
logical 0 disable it.
A logical 1 enables the TV display and we can output composite SYNC signal to HSYNC pin.

A logical 1 reverses the pixel data that sends to the panel for text mode .
A logical 1 reverses the pixel data that sends to the panel for graphic mode .
LCD panel has low response time character, TP6508 provides flexible choice
for blinking rate.

In panel text mode, when foreground RGB and background RGB mapping to the close gray level. It
will produce ambiguous phenomenon. When this bit is a logical 1, TP6508 will compare foreground
and background mapping gray level. If foreground gray level is larger than background gray level,
TP6508 forces foreground to the maximum gray level , background to the minimum gray
will eliminate ambiguous situation. If the bit 6 of previous register set to logical 1 , then this bit is not
valid .
When this bit is a logical 1, TP6508 provides 16 gray level without passing through gray palette for
text mode . In this mode, Red, Green, Blue, and Intensity , four bits can make 16 gray level without
losing color, mono mapping relation .
When this bit is a logical 1, TP6508 provides 16 gray level without passing through gray palette for 16
color graphic mode.
On LCD panel, a narrow cursor may difficult to observe. A logical 1 forces a full display cursor for
easy find out and ignores the cursor sharp setting.
