What's the minimum time to be log by the real time clock?

Latest Updated:05/28/2013

Question:

Is the minimum unit of time that can be logged by the real-time clock the value of the 64-Hz counter (1/64 Hz ≒ 15.6 ms)?

Answer:

Yes.
The minimum time that can be read is the 64-Hz counter (R64CNT). After the least significant F64HZ bit is set to 1 from 0, the period until the next setting of 1 from 0 is 15.6 ms. The period of 0 or 1 is 7.8 ms.
