Access:
This register acts as a double buffer for the CDTY value. This prevents an unexpected waveform when modifying the wave-
form duty-cycle.
Only the first 16 bits (channel counter size) are significant.
• CDTYUPD: Channel Duty-Cycle Update
Defines the waveform duty-cycle. This value must be defined between 0 and CPRD (PWM_CPRx).
