LCD
SEGMENT DRIVER OUTPUTS
The LCD drive section includes 24 segment outputs
(S00 to S23) which should be connected directly to the
LCD. The segment data bits are multiplexed to the outputs
in accordance with the backplane signals. If less than the
24 segment outputs are required then the unused driver
outputs should be left open.
6.7.6
B
ACKPLANE OUTPUTS
The LCD drive sections includes 4 backplane outputs
(BP0, BP1, S23/BP2 and S22/BP3) which should be
connected directly to the LCD. These backplane output
signals are generated in accordance with the selected
LCD drive mode.
If less than 4 backplane outputs are required then the
unused backplane driver outputs should be left open.
6.7.7
LCD
SEGMENT DISPLAY REGISTERS
There is a one-to-one relationship between the LCD
segment register bits and the segment outputs.
A segment register bit which is set to:
Logic 1 indicates the ‘ON’ state of the corresponding
LCD segment.
Logic 0 indicates the ‘OFF’ state of the corresponding
LCD segment.
Table 23 shows the display register bit map.

These bits are not connected to a segment and can be used for other purposes.
