Write commands of my DFCM module are returning error code (FFF4) -12. What does this mean?

The FFF4 (decimal -12) error code indicates that the reply data does not match the requested byte count.

An issue with firmware version 1.42 caused all write commands to report a -12 (FFF4). Any version MVIXX-DFCM version 1.44 or greater has corrected the false reporting of this error on write commands.
