Default Value: 0b  

This bit enables the output of the General Control Packet. GCP is different from other 

DIPs in that much of the payload is automatically reflected in the packet, and therefore 

a DIP buffer for GCP is not needed. Please refer to the GCP payload register for payload 

details. Writes to this bit take effect immediately. This bit should not be enabled for 8bpc 

mode if at least one of the other HDMI ports is enabled in 12bpc mode.

Default Value: 0001b Enable AVI DIP  

These bits enable the output of a given data island packet (DIP) type. It can be updated 

while the port is enabled and is immediately updated (not double-buffered). Within 2 

vblank periods, the DIP is guaranteed to have been transmitted.

This field is used during programming of different DIPs. These bits are used as an index 

to their respective DIP buffers. The transmission frequency must also be written when 

programming the buffer.

These bits dictate the frequency of Video DIP transmission for the DIP buffer index 

designated in bits 20:19. When writing Video DIP data, this value is also latched when 

the first DW of the Video DIP is written. When read, this value reflects the Video DIP 

transmission frequency for the Video DIP buffer designated in bits 20:19. This field shall 

be ignored for Gamut Metadata Packet transmission.
