Normal 4:4:4 Input Format (RGB or YCbCr) Input ID = 0
An input format of RGB 4:4:4 or YCbCr 4:4:4 can be selected by setting the input ID (R0x15[3:1]) to 0b000. The input color space (CS)
must be selected by setting R0x16[0] to 0b0 for RGB or 0b1 for YCbCr. There is no need to set the input style (R0x16[3:2]).

YCbCr 4:2:2 Formats (24 Bits, 20 Bits, or 16 Bits) with Separate Sync, Input ID = 1
An input with YCbCr 4:2:2 with separate syncs can be selected by setting the Input ID (R0x15[3:1]) to 0b001. The input CS (R0x16[0])
must be set to 0b1 for proper operation. The data bit width (24 bits, 20 bits, or 16 bits) must be set with R0x16[5:4]. The three input pin
assignment styles are shown in Table 11. The input style can be set in R0x16[3:2].
