FORCE ACQ1 to FORCE ACQ0
FORCE ACQ<1:0>:
00 = automatic selection
01 = force 525 timing, force 525 Teletext standard
10 = force 625 timing, force 625 Teletext standard
11 = force 625 timing, force 525 Teletext standard
FORCE DISP<1:0>:
00 = automatic selection
01 = force display to 525 mode (9 lines per row)
