The OTP has a flag in the OTP header that will disable the debugger module (the JTAG enable flag) if this flag is burned to disabled then the OTP will no longer be accessible via JTAG. Off course there are always ways for someone to break into the SoC but you can always make things difficult for someone to crack.
Hi BigBobby,
