Hi Kari,

yes, you can split timer 0 in this way, that TH0 was the timer and TL0 can be a timer or counter.

But then T1 can only be used as timer or counter without interrupt capability.


I use this on my frequency meter (with AT89C2051), where TH0 was the time base, TL0 count the input frequency behind the external prescaler for high frequencies (...125MHz) and T1 count the input frequency directly for low frequencies (0.5Hz...).
It works great (written in C).
