Read Protection

Hi all,
I was searching for “read protection” of FEZ devices, and I found USBizi User Manual that says “If read protection is needed, the user can use the P command”. But I couldn’t get info about Spider, Hydra and Cerberus. I will be appreciated if someone explains.

Thanks.

Protection is only an option for premium offers, like USBizi and EMX (and their based FEZ boards)

Thanks a lot for fast reply, Gus.
