TCN75A
5.3.2
The TCN75A has an 8-bit read/write 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.
