List of access control attributes. They're needed to reference the channel's transfer channel descriptor (TCDn). When a read or write access occurs to any fields in the TCDn, if the system mode has sufficient privileges as defined by DMA_CHACR,the access completes. Otherwise, the access aborts and terminates in an error.
