Name
NTPAL: Switches between NTSC and PAL.
MODE2~MODE0: Switches output format.
RGBC: Switches the ADC clamp level for Cb and Cr.
VLINSEL: Sets the number of vertical lines.
HDSELB: Switches HD output signal.
Bit
0 (default): NTSC
0 (default): The ADC clamp level is 16 LSB for Y (for 8-bit conversion) and 128 LSB for Cb and Cr
1: The clamp level for Y, Cb and Cr is 16 LSB (for 8-bit conversion) (for RGB)
1: Any value from 1 to 1023 (Set using bits VLIN9~VLIN0 in Sub-Addresses 08H and 09H.)
0 (default): Variable HD output timing
0 (default): 525 (when NTPAL = 0) or 625 (when NTPAL = 1)
The clamp level is the pedestal clamp.
