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;
4~18
S1~S15
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
19~26
S16/KR7~
S23/KR0
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.
