Information

The PORT module generates a single DMA request that asserts when the interrupt status
flag is set for any enabled DMA request in that port. The DMA request negates after the
DMA transfer is completed, because that clears the interrupt status flags for all enabled
DMA requests.
During Stop mode, the interrupt status flag for any enabled interrupt is asynchronously
set if the required level or edge is detected. This also generates an asynchronous wakeup
signal to exit the Low-Power mode.
