PCF8578
LCD row/column driver for dot matrix graphic displays
In READ mode, indicated by setting the read/write bit HIGH, data bytes may be read from
the RAM following the slave address acknowledgement. After this acknowledgement the
master transmitter becomes a master receiver and the PCF8578 becomes a slave
transmitter. The master receiver must acknowledge the reception of each byte in turn. The
a. Master transmits to slave receiver (WRITE mode)
b. Master reads after sending command string (write commands; read data)
c. Master reads slave immediately after sending slave address (READ mode)
