2 STATUS_DONE
This is an interrupt source register.
This flags when the DMA Channel has completed a transfer suc-
cessfully on its side.
A completed transfer is defined as when the DMA Channel reaches
its limit; Memory Start Address equals Memory End Address.
A completion due to a Hardware Flow Control Terminate will not
flag this interrupt.
1=Memory Start Address equals Memory End Address
0=Memory Start Address does not equal Memory End Address

RESET
1 STATUS_FLOW_CONTROL
This is an interrupt source register.
This flags when the DMA Channel has encountered a Hardware
Flow Control Request
after the DMA Channel has completed the
transfer. This means the Master Device is attempting to overflow the
DMA.
1=Hardware Flow Control is requesting after the transfer has com-
pleted
0=No Hardware Flow Control event
