IC Prog with CP and CPD !

[dadleit]

Hi for all,
it's possible that I use CP and CPD with IC Prog when I put in the PIC the file flash of SimEmu ?
I have tried but after is not possible write the ADN in the flash or the name of the provider for tel. 1 to tel. 8 and the security for PIN (+ 3 attempts) don't work !.
It's possibile to use IC Prog with CP from 0000h to for example 1000h ?
This is good because would like to use above all this functions so if I loose my sim, there are not problem for my ADN write in the flash and don't visible for the man that can find my SIM !!

Do not enclose protection given.
Only programmer in assembly file can this to do!

As one time I explained, don't uncheck the WRT because all the internals updates to flash are forbidden.
In the flash reside the last part of phonebook, descriptions of positions and PINs/PUK's tries.

It is not possible to protect flash areas for reading via ICProg and maintain internals updates. See Microchip docs.

For this reason, the KI/PINs/PUKs are located in the internal EEPROM because it is possible to protect it and allow to program update this area.

What mean that is not possible ?
Tnx

The hardware does not allow to do this. See Microchip docs if you want to undestand more.

This table was extracted of 16F87x doc of Microchip manufacturer.

 1       1     1   All program memory Yes      Yes      Yes       Yes

When the ICSP read is not allowed, also the Internal Writes are not allowed.
