Enable the fifth toggle position for all V-signals in each group.
Starting polarities for each V-output signal (Group A).
Starting polarities for each V-output signal (Group D).
Start position of selected V-Pattern Group A.
Number of repetitions for V-Pattern Group A for first lines.
Number of repetitions for V-Pattern Group A for third lines.

Description
CLPOB start polarity.
PBLK start polarity.
1 = enable HOLD function for each VPAT group (A, B, C, D).
1 = enable FREEZE/RESUME for each VPAT group (A, B, C, D).
Combine multiple VPAT groups together in one sequence. Set register
equal to 0x01 to enable.
Defines V-alternation repetition mode.
00 = single pattern alternation for all groups.
01 = two pattern alternation for all groups.
10 = three-pattern alternation for Group A. Groups B, C, and D
follow pattern {0, 1, 1, 0, 1, 1…}.
11 = four-pattern alternation for Group A. Two-pattern alternation
for Groups B, C, and D.
Enable use of last repetition counter for last repetition length of each group.
Selection of HBLK modes.
00 = HBLK Mode 0 (normal six-toggle operation).
01 = HBLK Mode 1.
10 = HBLK Mode 2. (Address 0x19 to Address 0x1E operate differently.)
11 = test only, do not access.
HD line length for even lines.
HD line length for odd lines.
Selects which two toggle positions are used by each V-output when they
are configured as VSG pulses (Miscellaneous Register Address 0x1C, fixed
register area).
0 = use Toggles 1, 2; 1 = use Toggles 3, 4.
HD length Bit [13] for even lines when 14-bit H-counter is enabled.
HD length Bit [13] for odd lines when 14-bit H-counter is enabled.
Starting polarities for each V-output signal (Group B).
Starting polarities for each V-output signal (Group C).
Select which group each XV1 ~ XV12 signal is assigned to.
00 = Group A, 01 = Group B, 10 = Group C, 11 = Group D.
[1:0]: XV1; [3:2]: XV2 … [23:22]: XV12.
Select which group each XV13 ~ XV24 signal is assigned to.
00 = Group A, 01 = Group B, 10 = Group C, 11 = Group D.
[1:0]: XV13; [3:2]: XV14 … [23:22]: XV24.
Selected VPAT group for Group A, from VPAT Group 0 ~ 31.
Selected VPAT group for Group B, from VPAT Group 0 ~ 31.
Selected VPAT group for Group C, from VPAT Group 0 ~ 31.
Selected VPAT group for Group D, from VPAT Group 0 ~ 31.
Length of selected V-Pattern Group A.
Number of repetitions for V-Pattern Group A for second lines.
Number of repetitions for V-Pattern Group A for fourth lines.
Start position of selected V-Pattern Group B.
Length of selected V-Pattern Group B.
