5.4.
AV MUTE STATUS
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 AVMUTE status received in the last General Control packet received.
Function
av_mute
Description
0 (default)
AVMUTE not set
1
AVMUTE set
5.5.
DEEP COLOR MODE SUPPORT
supports HDMI streams with 24-bits per sample and deep color modes. The addition of a video FIFO (refer to Section
more details) allows for the robust support of these modes.
The deep color mode information that the
extracts from the general control packet can be read back from
is possible to override the deep color mode that the
unpacks from the video data encapsulated in the processed HDMI stream. This
is achieved by configuring the
and
controls.
deep_color_mode[1:0]
, HDMI RX Map,
Address 0xE20B[7:6] (Read Only)
This control is a readback indicating the deep color mode information extracted from the general control packet.
Function
deep_color_mode[1:0]
Description
00 (default)
8-bits per channel
01
10-bits per channel
10
12-bits per channel
11
16-bits per channel (not supported)
override_deep_color_mode
, HDMI RX Map,
Address 0xE240[6]
This bit is used to override the Deep Color mode.
Function
override_deep_color_mode
Description
0 (default)
The HDMI section unpacks the video data according to the deep-color information extracted from the
General Control packets. (Normal operation)
1
Override the deep color mode extracted from the General Control Packet. The HDMI section unpacks
the video data according to the Deep Color mode set in DEEP_COLOR_MODE_USER[1:0].
deep_color_mode_user[1:0]
, HDMI RX Map,
Address 0xE240[5:4]
This control is used to manually set the Deep Color mode. The value set in this register is effective when override_deep_color_mode is set to
1.
Function
deep_color_mode_user[1:0]
Description
00 (default)
8 bits per channel
01
10 bits per channel
10
12 bits per channel
11
16 bits per channel (not supported)
Notes:
•
Deep color mode can be monitored via the deepcolor_mode_chng edge sensitive interrupt in the IO Map, which indicates if the
color depth of the processed stream has changed.
•
The
can be configured to trigger an interrupt when the deepcolor_mode_chng edge sensitive interrupt in the IO Map
changes from 0 to 1.
