In the Reed-Solomon II IP configuration, can I select Encoder and change the Number of symbols per codeword (codeword length N) to a setting other than "Up to 255"?

In this IP, the number of symbols to be included in a codeword is specified dynamically for each codeword.

The number of symbols to be included in a codeword is specified dynamically for each codeword by asserting the end of packet (EOP) signal high at the last symbol of the information data sequence to be sent on the input side.
There is no way to specify a fixed value for the IP, so please provide a simple counter circuit outside the IP for control.
