bits 0 and 1 of four successive display RAM addresses. In the 1 : 3 multiplex drive mode
these bits are placed in bits 0, 1 and 2 of three successive addresses, with bit 2 of the third
address left unchanged. This last bit may, if necessary, be controlled by an additional transfer
to this address but care should be taken to avoid overriding adjacent data because full bytes
are always transmitted. In the 1 : 4 multiplex drive mode the eight transmitted data bits are
placed in bits 0, 1, 2 and 3 of two successive display RAM addresses.

IIC-BUS DESCRIPTION
The IIC-bus is for 2-way, 2-line communication between different ICs or modules. The
two lines are a serial data line (SDA) and a serial clock line (SCL). Both lines must be
connected to a positive supply via a pull-up resistor when connected to the output stages of a
device. Data transfer may be initiated only when the bus is not busy.
Bit transfer
One data bit is transferred during each clock pulse. The data on the SDA line must
remain stable during the HIGH period of the clock pulse as changes in the data line at this
time will be interpreted as control signals.
