Clock And Data Termination Control; Av Mute Status; Deep Color Mode Support - Analog Devices ADV8003 Hardware Manual

freqtolerance[3:0], HDMI RX Map, Address 0xE20D[3:0]
Sets the tolerance in MHz for new TMDS frequency detection. This tolerance is used for the audio mute mask mt_msk_vclk_chng and
the HDMI status bit new_tmds_frq_raw.

5.3. CLOCK AND DATA TERMINATION CONTROL

The ADV8003 provides the
clock_terma_disable, HDMI RX Map, Address 0xE283[0]
This control is used to disable clock termination on port A. It can be used when term_auto is set to 0.
Function
clock_terma_disable

5.4. AV MUTE STATUS

av_mute is used to indicate the status of the avmute bit in the general control packet. As with the TMDS clock detection bits, this register
bit can be polled by the system software and the appropriate configuration done.
av_mute, HDMI RX Map, Address 0xE204[6] (Read Only)
This bit is a readback of the AVMUTE status received in the last General Control packet received.
Function
av_mute

5.5. DEEP COLOR MODE SUPPORT

The ADV8003 supports HDMI streams with 24-bits per sample and deep color modes. The addition of a video FIFO (refer to Section 5.6
for more details) allows for the robust support of these modes.
The deep color mode information that the ADV8003 extracts from the general control packet can be read back from
deep_color_mode[1:0]. It is possible to override the deep color mode that the ADV8003 unpacks from the video data encapsulated in the
processed HDMI stream. This is achieved by configuring the
deep_color_mode[1:0], HDMI RX Map, Address 0xE20B[7:6] (Read Only)
This is a readback of the deep color mode information extracted from the general control packet.
