C Fast-mode Plus
Data transfer from a slave transmitter to a master receiver. The first byte (the slave
address) is transmitted by the master. The slave then returns an acknowledge bit.
Next follows the data bytes transmitted by the slave to the master. The master returns
an acknowledge bit after all received bytes other than the last byte. At the end of the
last received byte, a “not acknowledge” is returned. The master device generates all
of the serial clock pulses and the START and STOP conditions. A transfer is ended
with a STOP condition or with a Repeated START condition. Since a Repeated
START condition is also the beginning of the next serial transfer, the I
be released.
