SEQUENCE
points to first entry of line count array (index 0)
generate 5 lines of line type index 2 (remember, it is the second entry of the line type
array); will be the first vertical raster pulse
generate 1 line of line type index 4; will be sync-black-sync-black sequence after the first
vertical pulse
generate 14 lines of line type index 6; will be the following lines with sync-black sequence
generate 540 lines of line type index 1; will be lines with sync and active video
generate 2 lines of line type index 6; will be the following lines with sync-black sequence
generate 1 line of line type index 5; will be the following line (line 563) with
sync-black-sync-black-null sequence (null is equivalent to sync tip)
generate 4 lines of line type index 2; will be the second vertical raster pulse
generate 1 line of line type index 3; will be the following line with sync-null-sync-black
sequence
generate 15 lines of line type index 6; will be the following lines with sync-black sequence
generate 540 lines of line type index 1; will be lines with sync and active video
generate 2 lines of line type index 6; will be the following lines with sync-black sequence;
now, 1125 lines are defined
points to first entry of line pattern array (index 1)

44
points to first entry of line type array (index 1)
use pattern entries 4 and 3 in this sequence (for sync and active video)
use pattern entries 4, 2, 4 and 2 in this sequence (for 2
use pattern entries 4, 2, 4 and 1 in this sequence (for sync-black-null-black-null)
use pattern entries 4, 1, 4 and 1 in this sequence (for sync-black-sync-black)
use pattern entries 4, 1, 4 and 2 in this sequence (for sync-black-sync-black-null)
use pattern entries 4 and 5 in this sequence (for sync-black)
