At any rate, what I want to know is this. A real time clock chip like
the NJU6355 has three pins, CE, a clock and a data I/O. Can I do a
hardware CE and still have full functionality of the RT clock using just
the clock and I/O pins?

As you can see, I run out of PIC pins if I can't.

I can't tell you if it will work, but i'm doubtfull. If it doesn't,
you can always think about using an I2C RTC like the PCF8593, which
only requires 2 pins.
