Repeat 4 and 5 until all the required data has been written or read.
Minimum number of data bytes for a read =1 (Shortest Message length is 2-bytes).
The master outputs a negative acknowledge for the data when reading the last byte of data.
This causes the slave to stop the output of data and allows the master to generate a STOP
condition.

Figure 21. Device addresses
Master generates a START condition to signal the start of new message.
Master outputs, MS bit first, a 7-bit device address of the slave the master is trying to
communicate with followed by a R/W bit.
a)
b)
The addressed slave acknowledges the device address.
Data transmitted on the bus

b)
Master generates a STOP condition or a repeated START.
Sensor write address 20
Sensor read address 21
R/W = 0 then the master (transmitter) is writing to the slave (receiver).
R/W = 1 the master (receiver) is reading from the slave (transmitter).
When a write is performed then master outputs 8-bits of data on SDA (MS Bit
first).
When a read is performed then slave outputs 8-bits of data on SDA (MS Bit First).
When a write is performed slave acknowledges data.
When a read is performed master acknowledges data.
