ALERT mode
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.
7.8.9 Other registers
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.
7.8.10 One-shot register
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).
