In order to change the data direction a repeated START condition is issued on the 1 SCL pulse after the

acknowledge bit of the word address transfer. After the reception of the device-read address, the slave becomes
the transmitter. In this state the slave transmits register data located by the previous received word address
vector. The master responds to the data byte with a not-acknowledge, and issues a STOP condition on the bus.

Sequential-Read is the extended form of Random-Read, as more than one register-data bytes are transferred
subsequently. In difference to the Random-Read, for a sequential read the transferred register-data bytes are
responded by an acknowledge from the master. The number of data bytes transferred in one sequence is
unlimited (consider the behavior of the word-address counter). To terminate the transmission the master has to
send a not-acknowledge following the last data byte and generate the STOP condition subsequently.

To keep the access time as small as possible, this format allows a read access without the word address transfer
in advance to the data transfer. The bus is idle and the master issues a START condition followed by the Device-
Read address. Analogous to Random-Read, a single byte transfer is terminated with a not-acknowledge after the

master sends a not-acknowledge following the last data byte and a subsequent STOP condition.
