I'll check that. B.t.w, what is "back-of-envelope" ??

Yes, I'd like some of the now power/speed functions of some of
the newer PIC's in a 8 pin package. Besides, I havn't found any
UART in any of the 8-pin PIC, correct ?

And it's "the othere side" that initiates the comm, so I don't
know if sleeping would work ?

If we expand the original question to include bitbang serial
comm, how slow could I go then ?
