42.7.13
Register Name:
Addresses:
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 16 bits (internal channel counter size) are significant.

PWM_CUPD[0..3]
Write-only
The duty-cycle (CDTY in the PWM_CDTYx register) is updated with the CUPD value at the
beginning of the next period.
The period (CPRD in the PWM_CPRDx register) is updated with the CUPD value at the beginning
of the next period.
