How to get continuous serial communications using minimal CPU usage?

Latest Updated:03/23/2009

Question:

How is it possible to get continuous serial communications using minimal CPU usage ?

Answer:

"By using the SCI in conjunction with the DTC or DMAC, it will be possible to get continuous transmission or reception via a SCI.

The interrupts generated by the SCI to indicate successful data transmission / reception can be taken by the DTC to update the TDR with new data to transmit / remove data from the RDR. The DTC will clear the relevant interrupt flags so that transmission / reception can continue."
