38.7.39 PWM Channel Duty Cycle Update Register
Name: PWM_CDTYUPDx [x=0..7]
Address: 0x40094208 [0], 0x40094228 [1], 0x40094248 [2], 0x40094268 [3], 0x40094288 [4], 0x400942A8 [5],
0x400942C8 [6], 0x400942E8 [7]
Access: 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.
• CDTYUPD: Channel Duty-Cycle Update
Defines the waveform duty-cycle. This value must be defined between 0 and CPRD (PWM_CPRx).
