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.
