Read protection

Dmitriy_Chernov · ‎Jan 19, 2022

Hi,

I am working with CYT2B73CAD.

Can I protect memory from external reading (via debugger) without changing lifecycle state?

If this is not possible, then how to call the BlowFuseBit command from the program code?

And this is also not possible, then can I call BlowFuseBit command from J-Link or I need specific programmer for it?

Thanks.
