Definition
to select refresh rate
0 : 60Hz
1 : 50Hz
to select input / output signals
[MODE1:MODE0]
00 : 525i/625i
01 : 525p/625p
10 : 1080i
11 : 720p
to appoint relation when to synchronize with HSYNC / VSYNC
0 : Data capture is done by the AK8823 timing.
1 : it is done by the compatible timing specified in CEA 861B.
to select the AK8823 Sync mode
0 : to be synchronized with HSYNC / VSYNC signals
1 : to be synchronized with EAV
to set on / off of 7.5 % set-up
0 : no set-up process is done.
1 : set-up process is done.
to output Black Burst Signal ( SYNC Signal Output only )
0 : normal output
1 : Black Burst Signal Output is enabled.
to output Color Bar Signal
0 : normal output
1 : Color Bar Signal is output.
When HDBB bit is set, HDBB is prioritized.
When EAVDEC is “ 1 “, set CEA861B to “ 0 “.
