39.7.12 PWM Sync Channels Update Period Update Register
Name: PWM_SCUPUPD
Address: 0x40020030
Access: Write-only
This register acts as a double buffer for the UPR value. This prevents an unexpected automatic trigger of the update of
synchronous channels.
• UPRUPD: Update Period Update
Defines the wanted time between each update of the synchronous channels if automatic trigger of the update is activated
(UPDM = 1 or UPDM = 2 in “PWM Sync Channels Mode Register” ). This time is equal to UPR+1 periods of the synchro-
nous channels.
