Universal 36 × 4 LCD segment driver

The example in Table 9 and Figure 6 illustrates the segment and backplane mapping of

the display in relation to the display RAM.

For example, in 1:4 multiplex drive mode, the backplanes are served by signals COM0 to

COM3 and the segments are driven by signals SEG0 to SEG35. Contents of addresses

04h to 08h are allocated to the first row (COM0) starting with the LSB driving the leftmost

element and moving forward to the right with increasing bit position. If a bit is logic 0, the

element is off, if it is logic 1 the element is turned on. All register content is LSB to MSB

left to right. Addresses 09h to 0Dh serve COM1 signals, addresses 0Eh to 12h serve

COM2 signals, and addresses 13h to 17h serve COM3 signals.

For displays with fewer segments/elements, the unused bits are ignored.
