In this operation, the master sends an address and two
data bytes to the slave device
procedure describes the single-byte write operation:
1) The master sends a START condition.
2) The master sends the 7-bit slave address plus a write
3) The addressed slave asserts an ACK on the data line.
4) The master sends the 8-bit register address.
5) The slave asserts an ACK on the data line only if the
6) The master sends eight data bits.
7) The slave asserts an ACK on the data line.
8) The master generates a STOP condition.
In this operation, the master sends an address and mul-
tiple data bytes to the slave device

device automatically increments the register address
after each data byte is sent, unless the register being
accessed is 0x00, in which case the register address
remains the same. The following procedure describes
the burst write operation:
1) The master sends a START condition.
2) The master sends the 7-bit slave address plus a write
3) The addressed slave asserts an ACK on the data line.
4) The master sends the 8-bit register address.
