PRST.
Transfer group pointer reset mode.
With PRST the way of resolving trigger events during an ongoing transfer
from the concerned transfer group can be configured.
1 =
The corresponding transfer group pointer (PCURRENT) will be reset to
the start address (PSTART) when a valid trigger event occurs at the
selected trigger source while a transfer from the same transfer group is
ongoing. I.e. every trigger event resets PCURRENT no matter whether
the concerned transfer group is in transfer mode or not. The trigger
events have priority over the ongoing transfer.
0 =
If a trigger event occurs during a transfer from the concerned transfer
group, the event is ignored and is not stored internally. The transfer
group transfer has priority over additional trigger events.
Bits 28
TGTD.
Transfer group triggered.
This bit is read-only.
1 =
The transfer group has been triggered and is either currently service or
waiting for servicing.
0 =
The corresponding transfer group has not been triggered or is no more
waiting for service.

Reserved
