The I
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. Data transfer may be initiated only when the interface bus is not
busy.
A device generating a message is a ‘transmitter’; a device receiving a message is the ‘receiver’. The
device that controls the message is the ‘master’ and the devices that are controlled by the master are
the ‘slaves’.
Both data and clock lines remain HIGH when the interface bus is not busy. A HIGH-to-LOW transition
of the data line while the clock is HIGH is defined as the start condition (S). A LOW-to-HIGH
transition of the data line while the clock is HIGH is defined as the stop condition (P)
