1.2 Input/Output Format
1.2.1 Input Data Format
The input of this IC complies with 16-bit 4:2:2 (YI[7:0] = Y-8bit, CI[7:0] = CbCr-8bit 4:2:2) format (input in
16-bit mode), 8-bit 4:2:2 (YI[7:0] = YCbCr-8bit 4:2:2, without SAV, EVA) format (input in 8-bit mode) and
ITU-R BT.656 conforming (YI[7:0] = YCbCr-8bit 4:2:2, with SAV, EAV) format (ITU-R BT.656 mode).
However, when INPR is set to 1, neither 8-bit input mode nor ITU-R BT.656 input mode can be selected.
The input format mode is set by an external pin MODE 2 or I2C-bus setting register DISEL (SUB:41h-bit[0]), or
R656 (SUB:41h-bit[1]).
Switching of an external pin and a register is accomplished by setting the I2C-bus setting register IRMON
(SUB:40h-bit[7]).
