Description
-Set the frame frequency of the Partial mode/ full colors.
- 1st parameter to 3rd parameter are used in line inversion mode.
- 4th parameter to 6th parameter are used in frame inversion mode.
- Frame rate=fosc/((RTNC + 20) x (LINE + FPC + BPC))
- 1 < FPC(front porch) + BPC(back porch) ; Back porch ≠0
Note: fosc = 333kHz
