The following sections describe the registers pertaining to interrupts, their status, and how to clear them. For each channel,
there are five types of interrupt sources:
This interrupt is generated on DMA transfer completion to the destination peripheral.
This interrupt is generated on DMA block transfer completion to the destination peripheral.
This interrupt is generated after completion of the last AMBA transfer of the requested single/burst transaction from the
handshaking interface on the source side.
If the source for a channel is memory, then that channel never generates a IntSrcTran interrupt and hence the correspond-
ing bit in this field is not set.
This interrupt is generated after completion of the last AMBA transfer of the requested single/burst transaction from the
handshaking interface on the destination side.
If the destination for a channel is memory, then that channel never generates the IntDstTran interrupt and hence the corre-
sponding bit in this field is not set.
This interrupt is generated when an ERROR response is received from an AHB slave on the HRESP bus during a DMA
transfer. In addition, the DMA transfer is cancelled and the channel is disabled.
