Access:
This register acts as a double buffer for the UPR value. This prevents an unexpected automatic trigger of the update of syn-
chronous 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
the synchronous channels.
