To be able to write 1 byte at a time to the register a special register address is added. The
8-bit write is done by first writing the upper 8 bits to the desired register and then writing
the lower 8 bits to the special register address (R0xF0). The register is not updated until
all 16 bits have been written. It is not possible to just update half of a register. In
Figure 11 on page 18, a typical sequence for 8-bit writing is shown. The second byte is
written to the special register (R0xF0).
To read one byte at a time the same special register address is used for the lower byte.
The upper 8 bits are read from the desired register. By following this with a read from the
special register (R0xF1) the lower 8 bits are accessed (Figure 12). The master sets the no-
acknowledge bits shown.
