Note 1: fc; High-frequency clock [Hz] fs; Low-frequency clock [Hz] *; Don't care
Note 2: Set the mode, source clock, and edge (selection) when the TC1 stops (TC1S = 00).
Note 3: If there is no need to use PWM6/PDO6/PPG6 as window gate pulse of TC1 always write "0" to TC6OUT.
Note 4: Make sure to write TC1CR2 "0" to bit 0 in TC1CR2.
Note 5: When using the event counter mode or pulse width measurement mode, set SEG to "0".
