49.5.1.1 VSYNC/HSYNC Data Timing
In the VSYNC/HSYNC synchronization, the valid data is captured with the active edge of the pixel clock (ISI_PCK), after SFD lines of vertical blanking and SLD pixel clock periods delay programmed in the ISI_CR.
The data timing using horizontal and vertical synchronization are shown in the following figure, with VSYNC and HSYNC active high and data sampled on the rising edge of the pixel clock.
