HSYN
Maximum frequency of LCDC_CLK is 48 MHz, which is controlled by Peripheral Clock Divider Register.
Maximum frequency of SCLK is HCLK / 5, otherwise LD output will be wrong.
VSYN, HSYN and SCLK can be programmed as active high or active low. In the above timing diagram, all
these 3 signals are active high.
Tpix is the pixel clock period which equals LCDC_CLK period * (PCD + 1).
Ts is the shift clock period. Ts = Tpix * (panel data bus width).
