Notes:
4. Conversion times are accumulative and depend on the total number of analog inputs configured.
For example, if only one analog input (fast mode) is configured, the conversion time will be 30ms; however,
if two analog (normal mode) and two RTD inputs are configured, the conversion time will be
100ms + 100ms + 300ms + 300ms = 800ms.
5. The analog value can indicate faults as shown below:
