15.10 LCD Registers
There are nine LCD registers. Four are control type registers: LCD control register (LCDCR), LCD
prescaler divider register (LCDDIV), LCD frame rate register (LCDFR), and LCD contrast control register
(LCDCCR). Five are read-only frontplane latch registers (LCDFL0:LCDFL4) that contain a latched version
of the frontplane data for the 40 frontplane drivers.
