Registers Setup Selection
The register selection follows the I2C address of a new
frame and must be followed by the DATA register. The
content of the register selection byte is not stored into the chip
and a new one shall be send for every DATA update. The low
nibble contains the selected register number as depicted in
Table 7. The high nibble is reserved for future use.
Table 7. REGISTER SELECTION CODE
The last code $0F is reserved for ON Semiconductor to
control the manufacturing test and access to this register is
not permitted outside the ON Semiconductor final test
facilities.
