Some probably-trivial-but-they-don't-seem-that-way-to-me questions:

Am I misunderstanding something basic when I wonder why you use a
32.768kHz crystal to count seconds with the TIMER1?  Don't 16 bits add
up to 65,536?  (This is from a comment in a microchip app note.) A
subsidiary question here is that I now have a TIMER1 attached to such
a crystal (32k), and it appears to tick at 1.8 seconds: what should I
check first? (I am using 22pF capacitors.)

Second question: What exactly is the problem with CALL statements from
an interrupt function?  Is there any danger to this when the interrupt
is only interrupting sleep?

And finally, and a little off-topic, I have, to my great relief,
finished constructing the protoype of my first project using an LCD.
Now I wonder what is the `real' way to connect my PIC's board to the
little LCD controller board (from Optrex). The LCD board has 14 little
copper pads along its edge, looking for all the world like they were
meant for some connector.  The problem is that I have no idea what
connector or what it's called.  Consulting catalogs has not helped so
far.  Perhaps somebody here can?

Many thanks,

-Tom
