I2C-bus description
The I2C-bus provides bidirectional 2-line communication
between different ICs. The SDA line is the serial data line
and the SCL the serial clock line. 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. The SAB9082 has the I2C-bus address 2CH. Valid
subaddresses are 00H to 18H, registers 15H to 18H are
reserved for future extensions.
I2C-bus control is according to the I2C-bus protocol: first, a
START sequence must be put on the I2C-bus. Then, the
I2C-bus address of the circuit must be sent, followed by a
subaddress. After this sequence, the data of the
subaddresses must be sent. An auto-increment function
gives the option of sending data of the incremented
subaddresses until a STOP sequence is sent. Table gives
an overview of the I2C-bus addresses. The data bits that
are not used should be set to zero.
