This table shows millivolt ranges.
NOTE:
1. Open Circuit Detect is always enabled for all TC types and may be disabled for
linear ranges.
2. On millivolt ranges, if Open Circuit Detect is enabled, this bit is set on Open
Circuit Detect or input FFFFh
3. Data format changes to unsigned if the output is requested in units of 0.1° F to
accommodate readings above 3276.8° F.
