Hello, this is the first time I sent request to this list. I'm trying to
interface a DAC with PIC16C84. I wanted to synchronize the DAC clock input
with PIC16C84 timing clock. How can I do that since PIC16C84 doesn't
provide a clock output?

Felix,

Why not use a timer interrupt and then stobe an i/o line? If your PIC
clock frequency is high enough the latency caused by the interrupt will
be minimal, adn the code is quite straightforward.

Hope this helps,
