DISEL
DISEL Initial value: 0; Setting range: 0 to 1
Sets input data format.
When R656 = 0, the input data format of 16-bit YCbCr 4:2:2 or 8-bit YCbCr 4:2:2 is selectable.
This register is valid when IRMON = 1. When IRMON = 0, external pin MODE2 performs the similar
operation.
R656I Initial value: 0; Setting range: 0 to 1
Sets input data format.
By setting R656I = 1, the input data format supports the ITU-R BT.656 standards regardless of DISEL
and MODE2 settings.

APN656 Initial value: 1, Setting range: 0 to 1
Automatic setting of 625/525
In ITU-R BT.656 input/output mode, the IC checks the format of 625 lines/525 lines and automatically
switches to the mode according to the setting VMD[0]. In this case, VMD[0] set due to external pin
setting or internal register setting is ignored.
