PCF8533
Universal LCD driver for low multiplex rates
After acknowledgement, the control byte is sent defining if the next byte is a RAM or
command information. The control byte also defines if the next byte is a control byte or
further RAM or command data (see Figure 16 and Table 8). In this way it is possible to
configure the device and then fill the display RAM with little overhead.
The command bytes and control bytes are also acknowledged by all addressed
PCF8533s connected to the bus.
The display bytes are stored in the display RAM at the address specified by the data
pointer and the subaddress counter; see Section 7.11 and Section 7.12.
