(1) Signal polarities may vary for some displays.
(1) The active data lines will vary with the type of TFT panel.
(2) The LCD panel clock is selected and scaled by the LCD controller and used to produce LCDCLK.
(3) The duration of the LCDLP is controlled by the HSW field in the TIMH register.
(4) The polarity of the LCDLP signal is determined by the IHS bit in the POL register.
