The PCA8533 is a peripheral device which interfaces to almost any LCD
multiplex rates. It generates the drive signals for any static or multiplexed LCD containing
up to four backplanes and up to 80 segments and can easily be cascaded for larger LCD
applications. The PCA8533 is compatible with most microcontrollers and communicates
via the two-line bidirectional I
display RAM with auto-incremental addressing, by hardware subaddressing and by
display memory switching (static and duplex drive modes).

... The subaddress counter is also incremented when the data pointer overflows. In cascaded applications each PCA8533 in the cascade must be addressed separately. Initially, the first PCA8533 is selected by sending the device-select command matching the first device's hardware subaddress. Then the data pointer is set to the preferred display RAM address by sending the load-data-pointer command ...

Page 18

... Next the load-data-pointer command is sent to select the preferred display RAM address of the second PCA8533. This last step is very important because during writing data to the first PCA8533, the data pointer of the second PCA8533 is incremented. In addition, the hardware subaddress should not be changed whilst the device is being accessed on the I 7 ...
