When I change the LIMIT[3:0] in the ERRCNTLIM register nothing seems to happen, why is this?

Question: In FX2, When I change the LIMIT[3:0] in the ERRCNTLIM register nothing seems to happen, why is this?

 

Answer:

The documentation for the LIMIT[3:0] incorrectly states that these values can be modified. The LIMIT[3:0] value is actually hardcoded to a value of 0100 (4) and cannot be modified. This has been changed in the FX2LP to make this value programmable.
