Table 13. Summary of V-Sequence Registers (see Table 9 and Table 10 for the HBLK, CLPOB, and PBLK Register Summary)
Register
Length Description
HOLD
4b
Use in conjunction with VMASK_EN.
1 = HOLD function instead of FREEZE/RESUME function.
VMASK_EN
4b
Enables the masking of V1 to V24 outputs at the locations specified by the FREEZE/RESUME registers.
1= enable masking for all groups. One bit for each set of Freeze and Resume Positions 1 to 4.
CONCAT_GRP
4b
Combines toggle positions of Groups A/B/C/D when enabled. Only Group A settings for start, polarity,
length, and repetition are used when this mode is selected.
0 = disable.
1 = enable the addition of all toggle positions from VPATSELA/B/C/D.
2 = test mode only. Do not use.
15 = test mode only. Do not use.
VREP_MODE
2b
Selects line alternation for V-output repetitions. Note separate control for Group A and Groups B/C/D.
0 = disable alternation. Group A uses VREPA_1, Groups B/C/D use VREP _EVEN for all lines.
1 = 2-line. Group A alternates VREPA_1 and VREPA_2. Groups B/C/D alternate VREP_EVEN and VREP_ODD.
2 = 3-line. Group A alternates VREPA_1, VREPA_2, and VREPA_3. Groups B/C/D follow a VREP_EVEN,
VREP_ODD, VREP_ODD, VREP_EVEN, VREP_ODD, VREP_ODD pattern.
3 = 4-line. Group A alternates VREPA_1, VREPA_2, VREPA_3, VREPA_4. Groups B/C/D follow 2-line alternation.
LASTREPLEN_EN
4b
Enables a separate pattern length to be used during the last repetition of the V-sequence. One bit for
each group (A, B, C, and D). Set bit high to enable. Group A is the LSB. Recommended value is enabled.
LASTTOG_EN
4b
Enables a final toggle position to be added at the end of the V-sequence. The toggle position is shared
by all V-outputs in the same group. One bit for each group. Set bit high to enable. Group A is the LSB.
HDLENE
13b
HD line length for even lines in the V-sequence.
HDLEN0
13b
HD line length for odd lines in the V-sequence.
VPOL_A
24b
Group A start polarity bits for each V1 to V24 output.
VPOL_B
24b
Group B start polarity bits for each V1 to V24 output.
VPOL_C
24b
Group C start polarity bits for each V1 to V24 output.
VPOL_D
24b
Group D start polarity bits for each V1 to V24 output.
GROUPSEL_0
24b
Assigns each V1 to V12 output to either Group A/B/C/D. Two bits for each signal. Bits [1:0] are for V1, Bits
[3:2] are for V2 … Bits [23:22] are for V12.
0 = assign to Group A, 1 = Group B, 2 = Group C, and 3 = Group D.
GROUPSEL_1
24b
Assigns each V13 to V24 output to either Group A/B/C/D. Two bits for each signal. Bits [1:0] are for V13,
Bits [3:2] are for V14 … Bits [23:22] are for V24.
0 = assign to Group A, 1 = Group B, 2 = Group C, and 3 = Group D.
VPATSELA
5b
Selected V-pattern for Group A.
VPATSELB
5b
Selected V-pattern for Group B.
VPATSELC
5b
Selected V-pattern for Group C.
VPATSELD
5b
Selected V-pattern for Group D.
VSTARTA
13b
Start position for the selected V-pattern Group A.
VSTARTB
13b
Start position for the selected V-pattern Group B.
VSTARTC
13b
Start position for the selected V-pattern Group C.
VSTARTD
13b
Start position for the selected V-pattern Group D.
VLENA
13b
Length of selected V-pattern Group A.
VLENB
13b
Length of selected V-pattern Group B.
VLENC
13b
Length of selected V-pattern Group C.
VLEND
13b
Length of selected V-pattern Group D.
VREPA_1
13b
Number of repetitions for the V-Pattern Group A for first lines (even).
VREPA_2
13b
Number of repetitions for the V-Pattern Group A for second lines (odd).
VREPA_3
13b
Number of repetitions for the V-Pattern Group A for third lines.
VREPA_4
13b
Number of repetitions for the V-Pattern Group A for fourth lines.
VREPB_ODD
13b
Number of repetitions for the V-Pattern Group B for odd lines.
VREPC_ODD
13b
Number of repetitions for the V-Pattern Group C for odd lines.
