Configuration register
The Configuration register is used to store the device settings such as Device Operation
mode, OS/INT Operation mode, OS/INT Polarity, and OS/INT Fault Queue.
The Configuration register allows the user to program various options such as conversion
resolution (see
operating mode, and shutdown mode. The user has READ/WRITE access to all of the bits
in the Configuration register. The entire register is volatile and thus powers-up in its default
state only.
Table 7.
Keys:
1. Indicates Operation mode; 0 = Comparator mode, and 1 = Interrupt mode (see
2. The OS/INT is active-low ('0').
