signals with SAV/EAV. These synchronization signals are chosen output by the firmware. These ports become GPO
until the firmware initializes after hardware reset.

The video output is based on the ITU-R BT.656 format. It is able to output horizontal and vertical synchronization
At the time of the odd field, OVVSYNC falls in the 4th clock after falling of OVHSYNC.
At the time of the even field, OVVSYNC falls in to the H/2+4th clock the OVHSYNC falling.
