10.5 Usage Note 
When the clock time base function is selected as the internal clock of TCA in active mode or sleep 
mode, the internal clock is not synchronous with the system clock, so it is synchronized by a 
synchronizing circuit. This may result in a maximum error of 1/φ (s) in the count cycle.
