How to measure a clock using the frequency measurement circuit?

Latest Updated:08/10/2012

Question:

I cannot measure a clock using the frequency measurement circuit.

Answer:

Set the multifunction timer pulse unit 2 module stop bit (MSTPCRA.MSTPA9) or the 16 bit-timer pulse unit 0 (unit 0) module stop bit (MSTPCRA.MSTPA13) to 0 (MTU and TPU module-stop are canceled).
Set the frequency measurement circuit module stop bit (MSTPCRC.MSTPC19) to 0 (frequency measurement circuit module-stop is canceled).
