MODE

ATSC mode 1080P (SMPTE 274M progressive) [HDTV]

ATSC mode 1080I (SMPTE274M interlaced) [HDTV]

ATSC mode 720P (SMPTE296M progressive) [HDTV]

Generic mode for HDTV [HDTV]

ATSC mode 480I (SDTV 525 lines interlaced) [SDTV]

ATSC mode 480P (SDTV 525 lines progressive) [SDTV]

VESA master [VESA]

VESA slave [VESA]

SDTV 625 interlaced [SDTV]

Generic mode for SDTV [SDTV]

[Null]

dtg1_frame_size(10:0):

Generic mode frame size

[011 0000 0000]

{dtg1_frame_field_size_msb 0x39(6:4) and dtg1_framesize_lsb 0x3A(7:0)}

Determines number of lines per frame when in generic mode

dtg1_field_size(10:0):

Generic mode field size

{dtg1_frame_field_size_msb 0x39(2:0) and dtg1_fieldsize_lsb 0x3B(7:0)}

[000 0010 0000]

Determines number of lines in field 1 when in generic mode. This number should be programmed higher than

frame_size for progressive scan formats.

dtg1_vesa_cbar_size(7:0):

Color bar pattern, width

[1000 0000]

{dtg1_vesa_cbar_size 0x3C(7:0)}

Sets the width of each color bar in the color bar test pattern. This test pattern is only available when the DTG is in

VESA mode.

C control

[0]

dac_i2c_cntl:

{dac_cntl_msb 0x3D(6)}

0 : DAC normal operation

1 : DAC inputs are fixed to values of <dac_cntl> registers.

dac1_cntl(9:0):

Direct input to G/Y DAC

dac2_cntl(9:0):

Direct input to B/Cb DAC

dac3_cntl(9:0):

Direct input to R/Cr DAC

DAC3 input value
