DMA Timers (DTIM0–DTIM3)
24.2.8 DMA Timer Event Registers (DTERn)
DTERn, shown in
DTERn[REF]. This reporting is done regardless of the corresponding DMA request or interrupt
enable values, DTXMRn[DMAEN] and DTMRn[ORRI,CE].
Writing a 1 to either DTERn[REF] or DTERn[CAP] clears it (writing a 0 does not affect bit value);
both bits can be cleared at the same time. If configured to generate an interrupt request, the REF
and CAP bits must be cleared early in the interrupt service routine so the timer module can negate
the interrupt request signal to the interrupt controller. If configured to generate a DMA request, the
processing of the DMA data transfer automatically clears both the REF and CAP flags via the
internal DMA ACK signal.

24-4, reports capture or reference events by setting DTERn[CAP] or
bits of the 32-bit timer in diagnostic software without requiring the timer to count through
its entire dynamic range. When set, the counter’s upper 16 bits mirror its lower 16 bits.
All 32 bits of the counter are still compared to the reference value.
