We would like to use INTB to tell the SOC that HDMI hot plug are detected.

Besides setting register 0x54 bit 6 =1 and register 0xC6 bit 0 = 1.

Any other setting is needed ?

Hello PYT,

You need also to enable global interrupt in reg 0xC6[0].

Hi Hamzeh,

Do i need to connect DS90UH949-Q1 to a deserializers like DS90UH940-Q1/DS90UH948-Q1 to make this function work ?

Yes, you do need a serializer and a deserializer.
