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 1st register byte. Analogous to Sequential Read an unlimited number of data bytes can
be transferred, where the data bytes has to be responded with an acknowledge from the master. For termination of the transmission the master
sends a not-acknowledge following the last data byte and a subsequent STOP condition.
