dtg1_spec_a(7:0):
Negative HSync width
{dtg1_spec_a 0x25(7:0)}
[00101100] = [44d]
Width of negative excursion of tri-level (HDTV mode)

{dtg1_spec_b 0x26(7:0)}
[01011000] = [88d]
Distance from end of active video to start of negative
sync (SDTV mode) or to negative-to-positive
transition of tri-level sync (HDTV mode).
dtg1_spec_c(7:0):
