Embedded Analog Input Specifications
Attribute
Value
Number of inputs
4 differential or single-ended
Analog normal operating ranges

(1)
The over-range flag will come on when the normal operating range is exceeded. The embedded HSC will continue to convert
the analog input up to the maximum full scale range. The flag automatically resets when within the normal operating range.
