forgot that oneThe clock source for this counter can be either the CPU clock (CCLK) or the XTAL1-2 oscillator This fives you the same effect as T0/T1 running off an external interrupt.
Everything works great now, but I don't know I have to count the frequency twice. I do not understand anyhow, what I would do would be to start the RTC (running off the external) and a timer (running off the internal) after, say 10.000 timer ticks, stop both and read the RTC. Now you have the relation between internal and external. Erik |
