YCbCr 4:2:2 Formats (24 Bits, 20 Bits, or 16 Bits) with Embedded Syncs, Input ID = 2
An input with YCbCr 4:2:2 with embedded syncs can be selected by setting the input ID (R0x15[3:1]) to 0b010. HS YNC and VSYNC are
embedded as Start of Active Video (SAV) and End of Active Video (EAV). The input CS (R0x16[0]) must be set to 0b1 for proper
operation. 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 Table 12. 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 ITU 656 running at 1× clock and double width.

YCbCr 4:2:2 Formats (Double Data Rate) Formats (12, 10, or 8 bits) with Separate Syncs, Input ID = 3
An input with YCbCr 4:2:2 DDR data and separate syncs can be selected by setting the input ID (R0x15[3:1]) to 0b011. The input CS
(R0x16 [0]) must be set to 0b1. The data bit width (12 bits, 10 bits, or 8 bits) must be set with R0x16[5:4]. The two input pin assignment
styles are shown in Table 13. The input style can be set in R0x16[3:2].
