Data transfer
A device generating a message is a “transmitter”, a device receiving a message is the “receiver”. The device that controls
the message is the “master” and the devices which are controlled by the master are the “slaves”. See Fig. 18.
19.5
Acknowledge
The number of data bits transferred between the start and stop conditions from the transmitter to receiver is not limited.
Each byte of eight bits is followed by one acknowledge bit. At the acknowledge bit the data line is released by the master
and 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
