PROTECT FUSE AND WRITE PROTECT PIC24HJ

[cfernandez]

Hi,

I am use PIC24HJ and I want to protect the code for READ (which ICD) for this I use PROTECT fuse, but I see that the disable the write protect bit and I cannot write.

I am develop a BootLoader and if I use PROTECT fuse cannot write the new program.

How to set PROTECT for read and enable Write Protect ???

Best Regards,

When an ICD is in use, the protect fuses are turned off. You cannot use an ICD with protect enabled.

There is a separate application note about the code protection on the 24HJ family from Microchip, and the details will depend on your exact chip. Normally though you would enable boot block write protection, and leave write protection off on the rest of the code. Look at the PROTECT_CODE, and PROTECT_USER fuses.

Best Wishes

I try with the PROTECT_HIGH fuse and put this:

Word 3L: 0003 PROTECT_HIGH
H: 0000

The 3 is enable the write.
