LCD Driver Output (1/3 Duty, 1/2 Bias, R/C Type)

Note:

The 52-pin QFP package does not support the charge pump (C type bias) of the LCD. The LCD bias type must

select the R type by option.

LCD Segments as Logical Output

The SEG0~SEG23 also can be optioned as logical output, once an LCD segment is optioned as a logical output, the

content of bit0 of the related segment address in LCD RAM will appear on the segment.

SEG0~SEG7 and SEG8~SEG15 are together byte optioned as logical output, SEG16~SEG23 are bit individually

optioned as logical outputs.
