Eight-Bit Write Sequence
To be able to write one byte at a time to the register
a special register address is added. The eight-bit write
is done by first writing the upper eight bits to the
desired register and then writing the lower eight bits to
the special register address (Reg0x80). The register is
not updated until all 16 bits have been written. It is not
possible to just update half of a register. In Figure11 a
typical sequence for eight-bit writing is shown. The
second byte is written to the special register (Reg
0x80).

Eight-Bit Read Sequence
To read one byte at a time the same special register
address is used for the lower byte. The upper eight bits
are read from the desired register. By following this
with a read from the special register (Reg0x80) the
lower eight bits are accessed (Figure 12). The master
sets the no-acknowledge bits shown.
