I'm trying to get the DMA set up on an XMEGA-A and the data sheet says for setting up the bits in CTRLA:
Bit 2 – SINGLE: Single-Shot Data transfer
Setting this bit enables the single-shot mode. The channel will then do a burst transfer of BURSTLEN bytes on the
transfer trigger. A write to this bit will be ignored while the channel is enabled.
I assume from this that this bit once set, remains set until the channel is reset? As setting this bit is ignored if the channel is enabled,
and the channel needs to be enabled just before being triggered into use, I assume that just subsequently setting the ENABLE bit without
the SINGLE bit set, will enable the channel but keep the channel in SINGLE mode?
