gcp[5] | Clear_AVMUTE | Refer to HDMI 1.4b Specification Section 5.3.6. |
All other fields for the source GCP, (for example, Pixel Packing Phase and Default Phase as described in HDMI 1.4b Specification Section 5.3.6) are calculated automatically inside the core. You must provide the bit-field values in the table above through the source gcp[5:0] port. The GCP on the Auxiliary Data Port will always be filtered.
