Bits 1:0 – WAVEGEN[1:0] Waveform Generation Mode

These bits select the waveform generation operation. They affect the top value, as shown in 33.6.2.6.1 Waveform Output Operations. They also control whether frequency or PWM waveform generation should be used. The waveform generation operations are explained in 33.6.2.6.1 Waveform Output Operations.

Note: This bit field is not synchronized.


Value	Name	Operation	Top Value	Output Waveform on Match	Output Waveform on Wraparound
0x0	NFRQ	Normal frequency	PER⁽¹⁾/Max.	Toggle	No action
0x1	MFRQ	Match frequency	CC0	Toggle	Toggle
0x2	NPWM	Normal PWM	PER⁽¹⁾/Max.	Set	Clear
0x3	MPWM	Match PWM	CC0	Set	Clear

1) This depends on the TC mode: In 8-bit mode, the top value is the Period Value register (PER). In 16-bit and 32-bit mode it is the respective Max. value.
