Channel continue capability. The channel continue capability allows software the flexibility of
having the DMA controller start with descriptors that have already been programmed while
software continues to build more descriptors in memory.
Channel abort capability. The software can abort a previously initiated transfer by setting the bit
MRn[CA]. The DMA controller terminates all outstanding transfers initiated by the channel
without generating any errors before entering an idle state.
