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.

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.
