This is the main reason I use a high bootloader, that plus lower interrupt latency avoiding the double jump the interrupt would have to conotent with. The protection problem is a limitation of the architecture of the PIC and varies by product.

There you can see a section Other Devices.

Even if there was you would need code that was compiled to not use the bootblock space. Make no mistake between my personality and my attitude. Distorted Sine output from Transformer 5.


But is it possible to “table-write protect” only a part of the memory block using some asm code?

So they need to be remapped. So we need to point to the required files to install it manually. Some told that there are some modifications to be made in the software settings to do the programming.
