Register Name:
Access Type:
Only the first 20 bits (internal channel counter size) are significant.
•
If the waveform is left-aligned, then the output waveform period depends on the counter source clock and can be
calculated:
If the waveform is center-aligned, then the output waveform period depends on the counter source clock and can be
calculated:
