Waveform Generation
Frequency (FRQ) Waveform Generation
Single-slope PWM Generation
synchronization prevents the occurrence of odd-length, non-symmetrical pulses for glitch-free
output.
The compare channels can be used for waveform generation on the corresponding port pins. To
make the waveform visible on the connected port pin, the following requirements must be
fulfilled:
Inverted waveform output is achieved by setting the invert output bit for the port pin.
For frequency generation the period time (T) is controlled by the CCA register instead of PER.
The waveform generation (WG) output is toggled on each compare match between the CNT and
CCA registers, as shown in
Figure 14-14. Frequency waveform generation.
The waveform frequency (f
where N represents the prescaler divider used. The waveform generated will have a maximum
frequency of half of the peripheral clock frequency (fclk
and no prescaling is used. This also applies when using the hi-res extension, since this
increases the resolution and not the frequency.
For single-slope PWM generation, the period (T) is controlled by PER, while CCx registers con-
trol the duty cycle of the WG output.

FRQ
1. A waveform generation mode must be selected.
2. Event actions must be disabled.
3. The CC channels used must be enabled. This will override the corresponding port pin
4. The direction for the associated port pin must be set to output.
