Vertical Sync Triggering (VS input)
The active edge of the VS pin used for vertical synchronization is selected by bit VSP.
VSP = 0: The falling edge is active. (Default Value)
VSP = 1: The rising edge is active.
Horizontal Sync Triggering (HSYNC input)
The active edge of the HSYNC pin used for horizontal synchronization is selected by bit HSP.
HSP = 0: The falling edge is active. (Default Value)
HSP = 1: The rising edge is active.
RGB Output Polarity (ROUT, GOUT and BOUT outputs)
The output polarity of pins ROUT, GOUT and BOUT is selected by bit RGBPOL.
RGBPOL = 0: RGB active at 1 (Default Value)
RGBPOL = 1: RGB active at 0
