dtg1_spec_e(8:0): Sync to active video (HDTV)/Color bar start (VESA)
{dtg1_spec_deh_msb 0x2B(6) and [0 1100 0000] = [192d]
dtg1_spec_e_lsb 0x2A(7:0)}
Distance from negative-to-positive transition of tri-level sync to start of active video (HDTV mode). In case color bars are activated in
VESA mode, this parameter specifies the start of the color bar with respect to the horizontal sync
dtg1_spec_h(9:0): Broad pulse duration (SDTV)
{dtg1_spec_deh_msb 0x2B(1:0) and [00 0000 0000]
dtg1_spec_h_lsb 0x2C(7:0)}
Duration of broad pulse (SDTV mode)
dtg1_spec_i(11:0): Full-line broad pulse duration (SDTV)
{dtg1_spec_i_msb 0x2D(3:0) and [0000 0000 0000]
dtg1_spec_i_lsb 0x2E(7:0)}
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 [000 0101 1000] = [88d]
dtg1_spec_k_lsb 0x2F(7:0)}
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 [0000 0101 1000] = [88d]
dtg1_spec_g_lsb 0x32(7:0)}
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 [0 0101 0010 0000] = [1312d]
dtg1_total_pixels_lsb 0x35(7:0)}
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 [000 0000 0001]
dtg1_linecnt_lsb 0x37(7:0)}
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.
