LCD Driver Output and Bias Circuit
The output number of the microcontroller LCD driver
can be 20 3 or 19 4 by options (ie., 1/3 duty or 1/4
duty). The bias type of LCD driver is R type, no exter-
nal capacitor is required. The LCD can be optioned as
pendent on options.
The SEG7~SEG18 also can be optioned as logical out-
puts. Each group of SEG7~SEG10, SEG11~SEG14

If LCD is turned on at HALT mode, the LCD outputs are dependent on LCD display memory.
If LCD is turned off at HALT mode, the power will be V3=V2=V1=V0=VDD

and SEG15~SEG18 can be optioned individually. Once
an LCD segment is optioned as a logical output, the con-
tents of bit 0 of the related segment address in LCD
RAM will appear on the segment.
