Hi,

my background is that of a programmer, not an e.engineer, although i do have
an a-level in electronics :-O .

I want to supply an (accurate) 25 Hz clock to my T0CKI pin, but i'm
struggling with how to generate the signal. I can't see an RC being good
enough- i'm looking for a frequency tolerance of < 0.01 %)

The sum total of my electronics knowledge is this:- crystal + oscillator
circuit, flip-flops to divide.

But there must be a slightly better way of doing it (maybe an IC that can
help), because a crystal at say 3.2768 MHz needs diving 17 times, which is a
lot of flip flops.

I know this is a rather basic question, so forgive me!!

Jon
