Read Only view of the Wait_For_Ready End toggle signals to DMA. One per channel
Read-only view of sense state of the 8 DMA channels. A value of 1 in any bit position indicates that a read
and compare command failed or a timeout occured for the corresponding channel.
Read-only view of DMA request line for 8 DMA channels. A toggle on any bit position indicates a DMA
request for the corresponding channel.
Read Only view of the Command End toggle signals to DMA. One per channel
