Register Name: PWM_CUPD[0..3]
Addresses: 0xFFFB8210 [0], 0xFFFB8230 [1], 0xFFFB8250 [2], 0xFFFB8270 [3]
Access Type: Write-only
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.

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.
