Note: *FS is full-scale error, defined as the difference between the actual value that triggers the transition to full-scale
and the ideal analog full-scale transition value. Full-scale error equals offset error plus gain error. Refer to the
Analog-to-Digital Converter chapter of the SmartFusion Programmable Analog User’s Guide for more
information.
