Input ID = 1: An input with YCbCr 4:2:2 with separate syncs can be selected by setting the Input ID (R0x15[3:0]) to 0x1. The
data bit width (24, 20, or 16 bits) must be set with R0x16 [5:4]. The three input pin assignment styles are shown in the table. The
Input Style can be set in R0x16[3:2].
Input ID = 2: An input with YCbCr 4:2:2 with embedded syncs (SAV and EAV) can be selected by setting the Input ID
(R0x15[3:0]) to 0x2. The data bit width (24 = 12 bits, 20 = 10 bits, or 16 = 8 bits) must be set with R0x16 [5:4]. The three input pin
assignment styles are shown in the table. The Input Style can be set in R0x16[3:2]. The only difference between Input ID 1 and
Input ID 2 is that the syncs on ID 2 are embedded in the data much like an ITU 656 style bus running at 1X clock and double
width.
