Clock time base
TMA
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/ø (s) in the
count cycle.
