RA4M1 Code protection

Question

Hello, 
 Hi, I'm closing a project based on Arduino R4 Minima (RA4m1), written with the Arduino IDE. How can I easily read/copy protect my code? Thanks. Giorgio

Hello, 
 The RA4M1 device has an ID code protection function so that the MCU can determine whether to permit the connection to the programmer/on-chip debugger. Only if the correct ID code is given to the device will the connection be allowed. 
 However I am not sure how and if Arduino IDE can support this function . Do you even use an on-chip debugger via the SWD connector or just the USB connector to program the device ?
