NOTES:
1. The LCD data pins can be programmed to be driven on either the rising or falling edge of the pixel clock
2. These LCD signals can toggle when L_PCLK_WR is not clocking (between frames). At this time, they are
L_PCLK_WR
L_FCLK_RD
L_LCLK_A0
L_LDD[17:0]
L_LDD[17:0]
(L_PCLK_WR).
clocked with the internal version of the pixel clock before it is driven out onto the L_PCLK_WR pin.
