For a single-byte write operation, send the slave address
as the first byte followed by the register address and
then a single data byte (see Figure 5).
For a burst write operation, send the slave address as
the first byte followed by the register address and then
the data bytes (see Figure 6).

For a single-byte read operation, send the slave address
with the read bit set, as the first byte followed by the reg-
ister address. Then send a Repeated START condition
followed by the slave address. After the slave sends the
data byte, send a not-acknowledge followed by a STOP
condition (see Figure 7).
For a burst read operation, send the slave address with
a write as the first byte followed by the register address.
Then send a Repeated START condition followed by the
slave address. The slave sends data bytes until a not-
acknowledge condition is sent (see Figure 8).
