HREF, horizontal reference signal; indicates 720 pixels valid data
on the expansion port. The positive slope marks the beginning of a
new active line. HREF is also generated during the vertical
blanking interval (see

Fine position adjustment in LLC2 steps via HDEL[1:0] 11h[5:4]
(see
Function of HL is selectable via HLSEL[13h[3]]:
HLSEL = 0: HL is standard horizontal lock indicator.
HLSEL = 1: HL is fast horizontal lock indicator (use is not recommended for sources with unstable timebase e.g. VCRs).
