Function
External request for DMA transfer
DMA acknowledgment output signal (active low) for
external request of DMA transfer
These signals are output when an external request of DMA
transfer is accepted.
DMA active output signal (active low) for external request
of DMA transfer
These signals are output during a normal DMA space
access.
DMA end output signal (low at the end of DMA transfer) for
external request of DMA transfer
These signals are output during the last DMA access to
