How do I protect OTP from read?

If I make a product with the DA14580, how do I protect the OTP so that a competitor can not read it and steal my code?

Hi BigBobby,

Hi BigBobby,

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.

Thanks MT_dialog
