when special VSEQALT_EN mode is enabled.
FREEZE2
13b
Pixel location where the V-outputs freeze or hold (see VMASK_EN). Also used as VALTSEL1_EVEN [12:0] register
when special VSEQALT_EN mode is enabled.

register when S within line for each XV1 to XV24 output when special VSEQALT_EN mode is enabled.
RESUME2
13b
Pixel location where the V-outputs resume operation (see VMASK_EN). Also used as VALTSEL1_EVEN [17:13]
register when special VSEQALT_EN mode is enabled.

Separate length for last repetition of vertical pulses. Must be enabled using LASTREPLEN_EN.
Should be programmed to a value equal to the VLENB register.
LASTREPLEN_C
13b
Separate length for last repetition of vertical pulses. Must be enabled using LASTREPLEN_EN.
Should be programmed to a value equal to the VLENC register.
LASTREPLEN_D
13b
Separate length for last repetition of vertical pulses. Must be enabled using LASTREPLEN_EN.
Should be programmed to a value equal to the VLEND register.
LASTTOG_A
13b
Optional fifth toggle position for the vertical signals. Must be enabled using LASTTOG_EN.
Note that the toggle position is common for all vertical signals.

VSEQALT_EN
1b
Special V-sequence alternation mode is enabled when this register is programmed high.
VALT_MAP
1b
Enables the use of FREEZE/RESUME register locations to specify the VALTSEL0 and VALTSEL1 registers. Must be
enabled if VSEQALT mode is enabled.
VALTSEL0_EVEN
18b
Select lines for special V-sequence alternation mode for even lines. Used to concatenate VPAT Groups A/B/C/D into
unique merged patterns. Setting is used to specify one segment, with up to a maximum of 18 segments.
VALTSEL1_EVEN
18b
Select lines for special V-sequence alternation mode for even lines. Used to concatenate VPAT Groups A/B/C/D into
unique merged patterns. Setting is used to specify one segment, with up to a maximum of 18 segments.
VALTSEL0_ODD
18b
Select lines for special V-sequence alternation mode for odd lines. Used to concatenate VPAT Groups A/B/C/D into
unique merged patterns. Setting is used to specify one segment, with up to a maximum of 18 segments.
VALTSEL1_ODD
18b
Select lines for special V-sequence alternation mode for odd lines. Used to concatenate VPAT Groups A/B/C/D into
unique merged patterns. Setting is used to specify one segment, with up to a maximum of 18 segments.
SPC_PAT_EN
1b
Enable special V-pattern to be inserted into one repetition of a VPATA series.
SPC_PAT_EN [0]: Set to 1 to enable VPATB to be used as special pattern insertion.
SPC_PAT_EN [1]: Set to 1 to enable VPATC to be used as special pattern insertion.
SPC_PAT_EN [2]: Set to 1 to enable VPATD to be used as special pattern insertion.
