5.3.2
The
Configuration register that allows the user to select the
different features. These features include shutdown,
ALERT output select as comparator or interrupt output,
ALERT output polarity, fault queue cycle, temperature
measurement resolution and One-shot mode (single
conversion while in shutdown). These functions are
described in detail in the following sections.
