Pulse-Width Modulator
The PWM can be programmed to select one of two clock signals as its source frequency. The selected
clock signal is passed through a divider and a prescaler before being input to the counter. The output is
available at the pulse-width modulator output (PWMO) external pin. Its timing diagram is shown in
Figure 42 and the parameters are listed in Table 22.

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 41, 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 41, SCLK is always active.
For T9 non-display region, VSYN is non-active. It is used as an reference.
XMAX is defined in pixels.
