Trigger Selector(TRGSEL)
The trigger selector is the circuit which chooses the one trigger and outputs the trigger signal to the peripheral
function from two or more triggers inputted from the peripheral function, the port, etc.
The trigger chosen from eight triggers by
[TSEL0CRn]
<INSELm> is outputted to the peripheral function of a
connection destination.
"Figure 2.1 Example of Trigger Selector Connection" is an example of connection DMA transmission end
interrupts to DMAC via trigger selector. The setup of input trigger selection, edge detection condition selection,
trigger output selection, and trigger output control is performed by
[TSEL0CR3]
.
