(panel clock)
(1) The active data lines will vary with the type of STN panel (4-bit, 8-bit, color, mono) and with single or dual frames.
(2) The LCD panel clock is selected and scaled by the LCD controller and used to produce LCDCLK.
(3) The duration of the LCDLP signal is controlled by the HSW field in the LCD_TIMH register.
(4) The Polarity of the LCDLP signal is determined by the IHS bit in the LCD_POL register.
