Acknowledge/Not acknowledge

The receiver must always acknowledge each byte sent in a data transfer. In the case of the slave-receiver and master-

transmitter, if the slave-receiver does not send an acknowledge bit, the master-transmitter can either STOP the transfer

or generate a repeated START to start a new transfer.

In the case of the master-receiver and slave-transmitter, the master generates a not acknowledge to signal the end

of the data transfer to the slave-transmitter. The master can then send a STOP or repeated START condition to begin

a new data transfer.

In all cases, the master generates the acknowledge or not acknowledge SCL clock pulse.
