  thank you for the pointer! Yes, I did look at RISC.pdf before sending the e-mail. Section 3.5 says the following, quoted verbatim:

"The only addition to the processor interface is the signal ben (byte enable) derived from the modifier bit v in memory instructions."

The words "active high" are missing here too. "Derived from" can mean anything. Also, in the RISC5 ben was derived from p an q, not from v. So it is less than clear how this paper refers to RISC5. 

Thank you,
