Any number of data bytes can be transferred from the transmitter to receiver between the START and the STOP
conditions. Each byte of eight bits is followed by one ACK bit from the receiver. The SDA line must be released by
the transmitter before the receiver can send an ACK bit. The receiver that acknowledges must pull down the SDA
line during the ACK clock pulse, so that the SDA line is stable low during the high pulse of the ACK-related clock
period. When a slave receiver is addressed, it must generate an ACK after each byte is received. Similarly, the
master must generate an ACK after each byte that it receives from the slave transmitter. An end of data is
signaled by the master receiver to the slave transmitter by not generating an acknowledge after the last byte has
been clocked out of the slave. This is done by the master receiver by holding the SDA line high. The transmitter
must then release the data line to enable the master to generate a STOP condition.
