(1) The activation edge of the control signals LCD_VSYNC and LCD_HSYNC may be programmed to either the rising or falling edge of the pixel clock through the LCD (RASTER_TIMING_2) register. In Figure 6-56 through Figure 6-59, all signal polarity and activation edges are based on the default LCD (RASTER_TIMING_2) register settings.
(2) S2 = SYSCLK2 cycle time in ns

Frame-to-frame timing is derived through the following parameters in the LCD (RASTER_TIMING_1) register:

  • Vertical front porch (VFP)
  • Vertical sync pulse width (VSW)
  • Vertical back porch (VBP)
  • Lines per panel (LPP)

Line-to-line timing is derived through the following parameters in the LCD (RASTER_TIMING_0) register:

  • Horizontal front porch (HFP)
  • Horizontal sync pulse width (HSW)
  • Horizontal back porch (HBP)
  • Pixels per panel (PPL)

.LCD_AC_ENB_CS timing is derived through the following parameter in the LCD (RASTER_TIMING_2) register:

  • AC bias frequency (ACB)

The display format produced in raster mode is shown in Figure 6-55. An entire frame is delivered one line at a time. The first line delivered starts at data pixel (1, 1) and ends at data pixel (P, 1). The last line delivered starts at data pixel (1, L) and ends at data pixel (P, L). The beginning of each new frame is denoted by the activation of I/O signal LCD_VSYNC. The beginning of each new line is denoted by the activation of I/O signal LCD_HSYNC.
