Random location, single data write
For the master writing to the slave the R/W bit is set to zero.
The register index value written is preserved and is used by a subsequent read. The write
message is terminated with a stop condition from the master.
Current location, single data read
For the master reading from the slave the R/W bit is set to one. The register index of the
data returned is that accessed by the previous read or write message.
The first data byte returned by a read message is the contents of the internal index value
and NOT the index value. This was the case in older V2W implementations.
Note that the read message is terminated with a negative acknowledge (A) from the master:
it is not guaranteed that the master will be able to issue a stop condition at any other time
during a read message. This is because if the data sent by the slave is all zeros, the SDA
line cannot rise, which is part of the stop condition.
