Clearing the EN Bit

If the user clears the EN bit, the message will be stopped and the DMA will return to its default configuration. This is also referred to as a hard stop, as the DMA cannot resume operation from where it was stopped.

Important: After the DMA message transfer is stopped, it requires an extra instruction cycle before the Stop condition takes effect. Thus, after the Stop condition has occurred, a source read or a destination write can occur depending on the source or destination bus availability.
