Part Number: RM57L843
Could any one tell me the lowest clock RM57L843 counter can read?
I referred datasheet it shows that:
tw(EXTCLKIN)H EXTCLKhigh-pulse duration 6 ns
tw(EXTCLKIN)L EXTCLK low-pulse duration 6 ns
Dose it mean if I call timer with this external clock, I can count the number of pulse with 6ns resolution ?
Thanks and Regards,

In reply to Chuck Davenport:
thanks for your rep.
I am not professional about the types of timer modules that you said, so I trust that telling you my application, is the best way.
I would like to measure the time of difference of arrival of RF signal, whose velocity is 3x10^8 m/s with 6ns resolution of that timer.
It will take a time to transmit from receiver to MCU and this time is much higher than signal transmission time. So with a timer with 6 ns, after subtracting communication transmission time, I can get signal transmission time
