8.8.4 Acknowledge
The number of data bytes transferred between the START and STOP conditions from
transmitter to receiver is unlimited. Each data 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 must 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 consideration). A master receiver must signal the end of a data transmission 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.
