4.3.7 Read operation
Once the slave-address and data direction bit is sent, the slave acknowledges the master.
The slave can then transmit multiple number of data bytes. Each transmitted data byte is
followed by an Acknowledgement from the master. If the master no longer wants to receive
further data from the slave, it would send No-Acknowledge (NACK). Afterwards, Master can
send a STOP condition to terminate the data transfer.
