manual hotplug assertion (ADV7619)

I have a question regarding the maual hotplug assertion. I have enabled manual hotplug using

0x68, 0x6c, 0xA1


I have de-asserted the HPA singal using the write

0x98, 0x20, 0x30


I have programmed the internal edid with the edid data.


I am enabling the HPA by writing

0x98, 0x20, 0xF8


However I do not see any hotplug happening. Hotplug will happen only if enable the internal edid active bit to high only.

Is this the correct behaviour?
