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 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 an end of data to the transmitter by not generating an
acknowledge bit 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.
Before any data is transmitted on the I
addressed first. The addressing is always carried out with the first byte transmitted after
the START procedure. The I
