CUPD: Channel Update Register
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.
When CPD field of PWM_CMRx register = 0, the duty-cycle (CDTY of PWM_CDTYx register) is updated with the CUPD
value at the beginning of the next period.
When CPD field of PWM_CMRx register = 1, the period (CPRD of PWM_CPRDx register) is updated with the CUPD value
at the beginning of the next period.
