Acknowledge.
Each byte of eight bits is followed
by one acknowledge bit. This acknowledge bit is a
low level put on the bus by the receiver, whereas
the master generates an extra acknowledge relat-
ed clock pulse.
A slave receiver which is addressed is obliged to
generate an acknowledge after the reception of
each byte. Also, a master receiver must generate
an acknowledge after the reception of each byte
that has been clocked out of the slave transmitter.
The device that acknowledges has to pull down
the SDA line during the acknowledge clock pulse
in such a way that the SDA line is a stable Low dur-
ing the High period of the acknowledge related
clock pulse. Of course, setup and hold times must
be taken into account. A master receiver must sig-
nal an end-of-data to the slave transmitter by not
generating an acknowledge on the last byte that
has been clocked out of the slave. In this case, the
transmitter must leave the data line High to enable
the master to generate the STOP condition.
