LFRAME Pulse Stop Offset [9:0]
These bits specify the stop offset of the vertical sync signal within a line, in 1 pixel
resolution.

GPIO Preset Enable
When this bit = 1, GPIO1 can be toggled once per line, GPIO0 and GPIO2 signals
should be programmed with the appropriate values with REG[3Ch], [3Eh] and [40h].
When this bit = 0, GPIO0, GPIO1 and GPIO2 signals are preset to defined values.
LSHIFT Polarity Swap
When this bit = 1, LSHIFT signal is falling trigger.
When this bit = 0, LSHIFT signal is rising trigger.
LSHIFT Mask
When this bit = 1, LSHIFT signal is enabled in non display period.
When this bit = 0, LSHIFT signal is masked in non display period.
GPIO0 / GPIO1 Swap
When this bit = 1, GPIO0 / GPIO1 signals are swapped.
When this bit = 0, GPIO0 / GPIO1 signals are not swapped.
PS Alternate
When this bit = 1, PS signal change alternatively.
When this bit = 0, PS signal remain the same.
CLS Double
When this bit = 1, number of CLS pulse remain the same.
When this bit = 0, number of CLS pulse will be doubled.
