LCD-Driving-Waveform Control (R02h) (POR = 0000h)
FLD: Set display in interlace drive mode to protect from flicker. It splits one frame into 3 fields and drive.
The following figure shows the gate selection when the 3-field invension is enabled and the output waveform of the 3-
field interlaced driving.

When FLD = 1, it is 3 field driving, which also limit VBP = 1.
When FLD = 0, it is normal driving.
