Bits 15:0 – SWTRIGn[15:0] Channel n Software Trigger [n = 15..0]

This bit is cleared when the Channel Pending bit in the Channel Status register (CHSTATUS.PEND) for the corresponding channel is either set, or by writing a ‘1’ to it. See CHSTATUS in the DMAC Register Summary from Related Links.

This bit is set if CHSTATUS.PEND is already ‘1’ when writing a ‘1’ to that bit. See CHSTATUS in the DMAC Register Summary from Related Links.

Writing a ‘0’ to this bit will clear the bit.

Writing a ‘1’ to this bit will generate a DMA software trigger on channel x, if CHSTATUS.PEND=0 for channel x. CHSTATUS.PEND will be set and SWTRIGn will remain cleared. See CHSTATUS in the DMAC Register Summary from Related Links.
