After this pin becomes “L”, AK8813/14 starts the internal initializing
sequence.
After initializing sequence, AK8813/14 is set NTSC mode, Rec.656

(Note1) At ITU-R.BT656 I/F mode operation, FID/VSYNC, HSYNC pins should be pulled up to VDD with
100k-ohm Resistor
(Note2) This device requires reset operation. Before resetting the state of the pin of I/O are unknown state. After
reset sequence, I/Opins (FID/VSYNC, HSYNC) turns Hi-Z states.
