Burst-Write Operation
For a burst-write operation, send the slave address as
the first byte followed by the register address and then
the data bytes (Figure 8).
Single Byte-Read Operation
For a single byte-read operation, send the slave address
with a write as the first byte followed by the register
address. Then send a repeated START condition fol-
lowed by the slave address with the read bit set. After
the slave sends the data byte, send a not-acknowledge
followed by a STOP condition (Figure 9).
Burst-Read Operation
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 with the read bit set. The slave sends
data bytes until a not-acknowledge condition is sent
(Figure 10).
