synchronization delay is between two and three system clocks. The corresponding DTMRn[CLK]
selects the clock input source. A programmable prescaler divides the clock input by values from
1 to 256. The prescaler output is an input to the 32-bit counter, DTCNn.
24.2.2 Capture Mode
Each DMA timer has a 32-bit timer capture register (DTCRn) that latches the counter value when
the corresponding input capture edge detector senses a defined DTINn transition. The capture edge
bits (DTMRn[CE]) select the type of transition that triggers the capture and sets the timer event
register capture event bit, DTERn[CAP]. If DTERn[CAP] is set and DTXMRn[DMAEN] is one,
a DMA request is asserted. If DTERn[CAP] is set and DTXMRn[DMAEN] is zero, an interrupt
is asserted.
24.2.3 Reference Compare
Each DMA timer can be configured to count up to a reference value, at which point DTERn[REF]
is set. If DTMRn[ORRI] is one and DTXMRn[DMAEN] is zero, an interrupt is asserted. If
DTMRn[ORRI] is one and DTXMRn[DMAEN] is one, a DMA request is asserted. If the free
run/restart bit DTMRn[FRR] is set, a new count starts. If it is clear, the timer keeps running.
24.2.4 Output Mode
When a timer reaches the reference value selected by DTRR, it can send an output signal on
DTOUTn. DTOUTn can be an active-low pulse or a toggle of the current output as selected by the
DTMRn[OM] bit.
