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

Waveform Generation Mode

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

These bits are not synchronized.
