24.2.9 DMA Timer Reference Registers (DTRRn)
Each DTRRn, shown in
free-running timer counter (DTCNn) as part of the output-compare function. The reference value
is not matched until DTCNn equals DTRRn, and the prescaler indicates that DTCNn should be
incremented again. Thus, the reference register is matched after DTRRn+1 time intervals.

Output reference event. The counter value, DTCNn, equals the reference value, DTRRn.
Writing a one to REF clears the event condition. Writing a zero has no effect.
Capture event. The counter value has been latched into DTCRn. Writing a one to CAP
clears the event condition. Writing a zero has no effect.
