23-0 PCNT(n) 0-FF FFFFh Period (n) Value. Provides the current period since the beginning of the last tooth active
edge seen by the HWAG (PCNT (n)).
This period would not be accurate due to the fact that the PCNT counter is running at VCLK2
and that the peripheral bus is running at VCLK. Then, the value will have changed when
used.
