Oh God... sorry again... pls do not consider the function "change_value" in
the version I just sent. Its just another test I was trying just when I got
your reply.
Anyway, you should have enough info so that someone can reproduce the
problem...

Hello Borut,
Thanks for the reply but pls see my second message. I misspelled the last
line in the email but it is correct in the program (I do use *p = 0x12).
I attached the full source for your reference this time. I use two LEDs to
debug my program in the device. I have one green LED in RA4 and another
orange LED in RB4. The green LED goes on with PORTA = 0x00 and goes off when
PORTA = 0x10. The same for the orange LED with PORTB.
With the attached source the green goes on. When I uncomment the *p = 0x12
line both LEDs remain off. I tested several times and I am sure both LEDs
are working ok and several other conditional tests worked fine. The
dereferenced read also seems to work okay ( gptrget1.c).
PS.: This is a test application I wrote in order to narrow the problem I
had with the original program (which is much longer).
I am still stuck with this.
I feel like I will try to re-design my code so that I don't need to use
pointer dereferenced writing of values.
Let me know if you find something else strange with this...
Cheers,
Guerra
