PIC18F452 how to apply code protection using programmer opt?

[dani]

Hello All,

I have a problem regarding applying Code protection of PIC18F452. I have written a code for PIC18F452 using Proton Plus and its program memory is almost fill i.e code 32070 editor shows.

According to my knowledge correct me if i am worng that CP0-CP1-CP2,CP3 bits of PIC18F452 register should be set to all zero to protect PIC18F452's code from read. But when i do this my PIC dont works. Although i have checked this thing when my code is not too much as 32070 (i.e programm memory nearly filled). then it works ok.

Where i am wrong..

You can do it from your firmware.
I am taking you are using C18 compiler.

For example:

#pragma config CP0 = OFF //Code Protection Block 0
