HDMI ACR PACKET TRANSMISSION
A mode has been added to the HDMI Tx to ensure more efficient transmission of audio samples in 176.4 kHz and 192 kHz modes. This ensures
ACR packets can get sent more frequently on the
for these modes than is the case for the equivalent modes on the ADV8003.
arc_eff_tran_en
, TX2 Main Map,
Address 0xF447[0]
When enable it ensures more efficient transmission of ARC packets and audio samples in 176.4kHz and 192kHz modes. This ensures ACR
packets can get sent at the right rate (~1ms).
