1.2.6.2.3.1 Video Timing
The video timing is programmable as shown in
. The HITV and VITV registers set the
horizontal and vertical frame sizes. When the target video is interlaced, set ITLC=1. Line per field is
VITV/2. Unequal line per field is optionally available. When UEL=1, line per field alternately toggles
between (VITV-1)/2 and (VITV+1)/2. The active video position is set by the AV registers.
