dtg1_spec_i(11:0):
Full-line broad pulse duration (SDTV)
{dtg1_spec_i_msb 0x2D(3:0) and dtg1_spec_i_lsb 0x2E(7:0)}
[0000 0000 0000]
Duration of full-line broad pulse (SDTV mode)
dtg1_spec_k(10:0):
End of active video to sync (SDTV)/end of broad pulse to sync (HDTV)
{dtg1_spec_k_msb 0x30(2:0) and dtg1_spec_k_lsb 0x2F(7:0)}
[000 0101 1000] = [88d]
Distance from end of active video to leading edge of sync (SDTV) or from end of broad pulse to negative-to-positive
transition of tri-level sync (HDTV)
dtg1_spec_k1(7:0):
End of active video in first half of line to center equalization pulse (SDTV)
{dtg1_spec_k1 0x31(7:0)}
[00000000]
Distance from end of active video in first half of line to center equalization pulse for SDTV line type ACTIVE_NEQ
dtg1_spec_g(11:0):
1/2 of line length (SDTV)
{dtg1_spec_g_msb 0x33(3:0) and dtg1_spec_g_lsb 0x32(7:0)}
[0000 0101 1000] = [88d]
Half the line length. Only used in the calculations of SDTV line types
dtg1_total_pixels(12:0):
Total pixels per line (SDTV/HDTV/VESA)
{dtg1_total_pixels_msb 0x34(4:0) and dtg1_total_pixels_lsb 0x35(7:0)}
[0 0101 0010 0000] = [1312d]
Total number of pixels per line. Used in all DTG modes
dtg1_field_flip:
FID/F polarity select
{dtg1_fieldflip_linecnt_msb 0x36(7)}
[0]
0 : DTG is initialized to field1 at active VS edge when a 0 is received on FID signal or F bit.
1 : DTG is initialized to field1 at active VS edge when a 1 is received on FID signal or F bit.
dtg1_linecnt(10:0):
DTG start line number
{dtg1_fieldflip_linecnt_msb 0x36(2:0) and dtg1_linecnt_lsb 0x37(7:0)}
[000 0000 0001]
Sets the starting line number for the DTG when Vsync input or V-bit is asserted (vertical display control)
dtg1_on:
DTG on/off
{dtg1_mode 0x38(7)}
[1]
0 : DTG output held to dtg_y_blank value
1 : DTG on
dtg1_pass_through:
DTG pass-through
{dtg1_mode 0x38(4)}
[0]
0 : Video data blocked during certain line types
1 : Video data passed during certain line types
See DTG Line Types Overview (Section 4.7.3) for details.
dtg1_mode(3:0):
DTG mode selection
{dtg1_mode 0x38(3:0)}
[0110]
Selects the operation mode of the DTG according to the following table. Each setting is either an SDTV, HDTV or
VESA format, as shown:
