PCF8536
Universal LCD low multiplex driver with 6 channel PWM generator
8.6 Display register
The display register holds the display data while the corresponding multiplex signals are
generated.
8.7 Backplane outputs
The LCD drive section includes eight backplane outputs: BP0 to BP7. The backplane
output signals are generated based on the selected LCD multiplex drive mode.
In 1:8 multiplex drive mode: BP0 to BP7 must be connected directly to the LCD.
In 1:6 multiplex drive mode: BP0 to BP5 must be connected directly to the LCD.
In 1:4 multiplex drive mode: BP0 to BP3 must be connected directly to the LCD.
8.8 Segment outputs
The LCD drive section includes up to 44 segment outputs (S0 to S43) which must be
connected directly to the LCD. The segment output signals are generated based on the
multiplexed backplane signals and with data resident in the display register. When less
segment outputs are required, the unused segment outputs must be left open-circuit.
The number of available segments depends on the multiplex drive mode selected and the
number of GPOs used. The table shows consecutive GPOs selected, but this is just for
simplicity of explanation. Any combination of GPOs may be used.
Table 32. Backplane and active segment combinations
Basic examples. GPO pins may be configured in any combination. Other LCD segment and GPO combinations are possible.
