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