Acknowledge (see Figure 6)
The number of data bytes transferred between the start and the stop
conditions from transmitter to receiver is not limited. Each byte of
eight bits is followed by one acknowledge bit. The acknowledge bit
is a HIGH level put on the bus by the transmitter whereas 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. Also a master 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, so that
the SDA line is stable LOW during the HIGH period of the
acknowledge related clock pulse, set–up and hold times must be
taken into account.
A master receiver must signal an end of data to the transmitter by
not generating an acknowledge on the last byte that has been
clocked out of the slave. In this event the transmitter must leave the
data line HIGH to enable the master to generate a stop condition.
