Signal Polarity and Triggering

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 (HFLY input)

The active edge of the HFLY 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
