ADV7391 625i Vertical Blank

Hi,

On a custom project, I use the ADV7391 in square pixel mode to generate PAL 625i.

I verified the vertical blanking and I noticed an non-compliance to the UIT-R BT.1700 (or ITU-R BT.470-6).

Indeed, on this standard, the "m" present 5 pulses.

Measured:

Is there a register that control this characteristic ?
