Is it at all possible that occasionally on power-up, the program in a PIC
(I'm using a 16c71) begins NOT at PCL=0?  In my program, all I have is some
setup code to initialize the ports, disable interrupts, and set some
literals.  Immediately after this code, I turn a LED on.  Sometimes when I
start up after powering the PIC down, I get no outputs at all, and the LED
doesn't even turn on.  I'm sure power is getting to the PIC, but it seems
not to start up at the beginning of the program sometimes.

Anyone have any ideas on this?  It's pretty frustrating to power up only to
have some odd sequence of code running, then have to continually power down
and up until it appears to work.

By the way, it didn't do this until I added some I^2C code in the program,
but this code isn't accessed until later in the program.  I'm wondering if
there might be something wrong with the port initialization with the memory
device attached.  I'm really grasping at straws looking for answers.

Thanks for any advice.
