The Universal Asynchronous Receiver Transmitter features a two-pin UART that can be used for communication and
trace purposes and offers an ideal medium for in-situ programming solutions.

Moreover, the association with peripheral DMA controller (PDC) permits packet handling for these tasks with processor
time reduced to a minimum.
