PWM_CDTYUPDx [x=0..3]

0x40020208 [0], 0x40020228 [1], 0x40020248 [2], 0x40020268 [3]

Write-only.

This register acts as a double buffer for the CDTY value. This prevents an unexpected waveform when modifying the waveform 
duty-cycle.

Only the first 16 bits (channel counter size) are significant.

Defines the waveform duty-cycle. This value must be defined between 0 and CPRD (PWM_CPRx).
