Read and write address BFh.
D[7:1] is not defined and defaults to logic 0.
D0: The ALERT output is in interrupt mode when this bit is LOW. The ALERT output is in
comparator mode when this bit is HIGH.
The Manufacturers ID register has a default value A1h (1010 0001) and a read address
FEh.
The Die Revision Code register has a default value 00h (0000 0000) and read address
FFh. This register will increment by 1 every time there is a revision to the die.
The one-shot register is used to initiate a single conversion and comparison cycle when
the device is in the standby mode; upon completion of the single conversion cycle, the
device returns to the standby mode. It is not a data register; it is the write operation that
causes the one-shot conversion. The data written to this register is not stored; an FFh
value will always be read from this register. To initiate a one-shot operation, send a
standard write command with the command byte of 0Fh (One-Shot Write Address).
