LCD Driver Output

LCD Segments as Logical Output

The SEG0~SEG15 also can be optioned as logical output, once an LCD segment is optioned as a logical output, the

content of bit 0 of the related segment address in LCD RAM will appear on the segment.

SEG0~SEG7 is together byte optioned as logical output, SEG8~SEG15 are bit individually optioned as logical outputs.
