I2C Serial Data Bus
The DS1374 supports the I2C bus protocol. A device
that sends data onto the bus is defined as a transmitter
and a device receiving data is a receiver. The device
that controls the message is called a master. The
devices that are controlled by the master are slaves. A
master device that generates the serial clock (SCL),
controls the bus access, and generates the START and
STOP conditions must control the bus. The DS1374
operates as a slave on the I2C bus. Connections to the
bus are made through the open-drain I/O lines SDA
and SCL. A standard mode (100kHz max clock rate)
and a fast mode (400kHz max clock rate) are defined
within the bus specifications. The DS1374 works in both
modes.
The following bus protocol has been defined (Figure 8):
Data transfer can be initiated only when the bus is
not busy.
During data transfer, the data line must remain sta-
ble whenever the clock line is high. Changes in the
data line while the clock line is high can be interpret-
ed as control signals.
