Register Name:
Access Type:
This register acts as a double buffer for the period or the duty cycle. This prevents an unexpected waveform when modify-
ing the waveform period or duty-cycle.
Only the first 20 bits (internal channel counter size) are significant.

The duty-cycle (CDTY in the CDTYx register) is updated with the CUPD value at the beginning of
the next period.
The period (CPRD in the CPRDx register) is updated with the CUPD value at the beginning of the
next period.
