Description

LCD common output; Output common signal to the LCD panel. Through a matrix with

pins S1~S23, a maximum of 69 segments can be displayed.

Three levels, VLCD, VEE, and GND, are output at 83Hz every 2ms. VEE is output

after SYSTEM RESET and CLOCK STOP are released, and a common signal is

output after the DISP OFF bit is set to “0”.

LCD segment output;

LCD segment output/Key return timing output;

Segment signal output pins for the LCD panel. Together with COM1, COM2, and

COM3, a matrix is formed that can display a maximum of 69 segments. The signals

for the key matrix and the segment signals from pins S16/KR7~S23/KR0 are output

on a time division basis. 4 X 8=32 key matrix can be created in conjunction with key

input ports K0~K3.
