Quick settimer question

Hi all,
work progresses on my current project (wellllll, one of the 4 or so.....so many ideas!)
Part of it needs a pwmout on a 28X2 fed back into itself to the settimer external counter input.

The quick question is:
Which pin on the 28X2 is definitely the external counter input?
The manual (page 223) says "...is incremented on every positive going edge detected on input 0."
Obviously the 28X2 doesn't have an input 0, so I'm guessing it's pin C.0 as this is labelled "timer clk". Can anyone confirm this is definitely the correct pin?

That is correct. On page 223 the manual also says, "The timer function can be used in two way - as an internal timer or as an external counter (input 0 (C.0) only)".

Has there been an update to the manual? Mine says input 0 - no mention of C.0.

Thanks Hippy, re-downloaded manual and staring me in the face!
