input

R data input pin for 24-bit RGB input

OSD data input pin when using the

OSD function.

When the OSDSW pin is HIGH, input

to the ROSD, GOSD, and BOSD pins

takes precedence over RGB, and the

data is converted.

Control pins used to select RGB (24-

bit), YUV (16-bit) or DAC Through as

the input mode.

Switches the mode between Video-

CD (HIGH) and CD-G (LOW).
