Note:
Ts is the SCLK period which equals LCDC_CLK / (PCD + 1). Normally LCDC_CLK = 15ns.
VSYN, HSYN and OE can be programmed as active high or active low. In Figure 46, all 3 signals are active low.
The polarity of SCLK and LD[15:0] can also be programmed.
SCLK can be programmed to be deactivated during the VSYN pulse or the OE deasserted period. In Figure 46, SCLK is
always active.
For T9 non-display region, VSYN is non-active. It is used as an reference.
XMAX is defined in pixels.
