The I
The two lines are the Serial Data line (SDA) and the Serial Clock Line (SCL). Both lines
must be connected to a positive supply via pull-up resistors. Data transfer may be initiated
only when the bus is not busy.
Each byte of eight bits is followed by an acknowledge bit. The acknowledge bit is a HIGH
level signal put on the bus by the transmitter during which time the master generates an
extra acknowledge related clock pulse. A slave receiver which is addressed must generate
an acknowledge after the reception of each byte.
