I've got a few NJU6355 real-time clock chips but no real data for them.
I have something working based on what little I could find on the WWW but
I need to know a couple more things to be sure it's officially in spec:

* When clocking bits in, does the chip take them on the rising edge of
the clock or the falling edge?  It appears that when clocking bits out,
they change on the falling edge.

* What's the maximum clock rate/setup time, etc?

* Does the chip need the R/W pin held for the entire shifting sequence?
It would be nice to be able to share it with Clock or Data, saving a PIC
pin, but my preliminary experiments at that were not successful.

Once I get this little "test program" in shape (it reads/writes the 6355
and presents the results in ASCII RS-232), I'd be glad to post it to the
list or send it to someone to put on a WWW site.
