Thank you for an early answer. 
The next part cannot understand me. 
Can you measure a clock of SX to 160MHZ at the time of 20MHZ? . 

The circuit where I took for an example inputs 20MHz into CLKin and inputs it into RA3,RA4 through resistance. 
By a method to send a prescaler and a timer, I decide the most suitable number of partitions I measure frequency in first time, and to be next. 
How much does the best measurement upper limit frequency of such a method become? 
nonnno[/quote]From what I remember when I was playing around with this about 50MHz is the absolute maximum regardless of what the SX is clocked at.
