The timing parameters are defined by the LIDD_CS0_CONF and LIDD_CS1_CONF registers, which are
described in
and
.
The timing configuration is based on an internal reference clock, MCLK. The MCLK is generated out of
LCD_CLK, which is determined by the CLKDIV bit in the LCD_CTRL register.
See your device-specific data manual for the timing configurations supported by the LCD controller.
