19. LCD controller/driver
The LCD controller/driver contains 24
× 8-bit display data memory and controls the LCD display with four common
output lines and 48 segment output lines. Three duty outputs can be selected to directly drive the LCD panel
(liquid crystal display).
Contains an LCD driving voltage split resistor. Moreover, the external division resistance can be connected.
A maximum of four common output lines (COM0 to COM3) and 48 segment output lines (SEG0 to SEG47)
are available.
Contains 24-byte display data memory (display RAM).
For the duty, 1/2, 1/3, or 1/4 can be selected (restricted by bias setting).
The LCD can directly be driven.
