SINGLE-CHIP 8-BIT CMOS MICROCOMPUTER
LCD DRIVE CONTROL CIRCUIT
The 3820 group has the built-in Liquid Crystal Display (LCD) drive
control circuit consisting of the following.
LCD display RAM
Segment output enable register
LCD mode register
Selector
Timing controller
Common driver
Segment driver
Bias control circuit
A maximum of 40 segment output pins and 4 common output pins
can be used.
Up to 160 pixels can be controlled for LCD display. When the LCD
enable bit is set to “1” after data is set in the LCD mode register,

Note :
LCDCK is a clock for a LCD timing controller.
the segment output enable register and the LCD display RAM, the
LCD drive control circuit starts reading the display data automati-
cally, performs the bias control and the duty ratio control, and dis-
plays the data on the LCD panel.
