Access:
This register can only be written if the bits WPSWS2 and WPHWS2 are cleared in
page
• SYNCx: Synchronous Channel x
0 = Channel x is not a synchronous channel.
1 = Channel x is a synchronous channel.
• UPDM: Synchronous Channels Update Mode
0 = Manual write of double buffer registers and manual update of synchronous channels. The update occurs at the begin-
ning of the next PWM period, when the bit UPDULOCK in
set.
1 = Manual write of double buffer registers and automatic update of synchronous channels. The update occurs when the
Update Period is elapsed.
2 = Automatic write of duty-cycle update registers by the PDC and automatic update of synchronous channels. The update
occurs when the Update Period is elapsed.
3 = Reserved.
• PTRM: PDC Transfer Request Mode
• PTRCS: PDC Transfer Request Comparison Selection
Selection of the comparison used to set the flag WRDY and the corresponding PDC transfer request.
