Sequence (hexadecimal) Comment
1C 12
generate 540 lines of line type index 1; will be lines with sync and
active video
02 60
generate 2 lines of line type index 6; will be the following lines with
sync-black sequence
01 50
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)
04 20
generate 4 lines of line type index 2; will be the second vertical raster
pulse
01 30
generate 1 line of line type index 3; will be the following line with
sync-null-sync-black sequence
0F 60
generate 15 lines of line type index 6; will be the following lines with
sync-black sequence
1C 12
generate 540 lines of line type index 1; will be lines with sync and
active video
02 60
generate 2 lines of line type index 6; will be the following lines with
sync-black sequence; now, 1125 lines are defined
Write to subaddress D2h (insertion is done into all three analog output signals)
00
points to first entry of line pattern array (index 1)
6F 33 2B 30 00 00 00 00 880 × value(3) + 44 × value(3); (subtract 1 from real duration)
6F 43 2B 30 00 00 00 00 880 × value(4) + 44 × value(3)
3B 30 BF 03 BF 03 2B 30 60 × value(3) + 960 × value(0) + 960 × value(0) + 44 × value(3)
2B 10 2B 20 57 30 00 00 44 × value(1) + 44 × value(2) + 88 × value(3)
3B 30 BF 33 BF 33 2B 30 60 × value(3) + 960 × value(3) + 960 × value(3) + 44 × value(3)
Write to subaddress D1h
00
points to first entry of line type array (index 1)
34 00 00 00
use pattern entries 4 and 3 in this sequence (for sync and active
video)
24 24 00 00
use pattern entries 4, 2, 4 and 2 in this sequence
(for 2 × sync-black-null-black)
24 14 00 00
use pattern entries 4, 2, 4 and 1 in this sequence
(for sync-black-null-black-null)
14 14 00 00
use pattern entries 4, 1, 4 and 1 in this sequence
(for sync-black-sync-black)
14 24 00 00
use pattern entries 4, 1, 4 and 2 in this sequence
(for sync-black-sync-black-null)
54 00 00 00
use pattern entries 4 and 5 in this sequence (for sync-black)
Write to subaddress D3h (no signals are directed to pins HSM_CSYNC and VSM)
00
points to first entry of value array (index 0)
CC 00
black level, to be added during active video
80 00
sync level LOW (minimum output voltage)
0A 00
sync level HIGH (3-level sync)
CC 00
black level (needed elsewhere)
