Hello...

        Can anyone help me with this problem. I am using the PIC16C65A for my
project.
I use MLAB 3.12 in simulation mode to do the programming. Since 65A is not
in the list
of processors  simulated by MLAB, I choose 74A. The problem I encounter is
that I
keep on getting periodic receive interrupt during the simulation. I really
wonder what
have I missed out. How can I get receive interrupt when there is nothing to
trigger
it? I wanted to use the USART receive interrupt but I just cannot figure
out why it
keep on interrupting me periodically with nothing to trigger it.

        Is there any configurations I need to set in MLAB or any registers I nee
d
to set?
I have turned of al the other unwanted interrupt ( at least I think ) by
setting the
values of INTCON to B'11010000', PIE1 to B'00100000' and PIE2 to
B'00000000'.
All assistance will be greatly appreciated. Pls. bear with me if the
question seem to be
elementary......
