When cascaded PCF85133 are synchronized, they can share the backplane signals from
one of the devices in the cascade. Such an arrangement is cost-effective in large LCD
applications since the backplane outputs of only one device need to be through-plated to
the backplane electrodes of the display. The other PCF85133 of the cascade contribute
additional segment outputs. The backplanes can either be connected together to enhance
the drive capability or some can be left open-circuit (such as the ones from the slave
in Figure 23) or just some of the master and some of the slave will be taken to facilitate the
layout of the display.
