Falling-edge Clock Reference

Rising-edge Clock Reference

The configuration of assertion of the data can be programmed on the falling or rising edge of the pixel clock.

The polarity and the pulse width of VOUT(x)_HSYNC and VOUT(x)_VSYNC are programmable, refer to Display Subsystem (DSS)

section in Peripherals chapter in the device TRM.

The VOUT(x)_PCLK frequency can be configured, refer to Display Subsystem section in Peripherals chapter in the device TRM.

x in VOUT(x) = 1 or 2.
