40. Universal Asynchronous Receiver Transmitter (UART)
40.1 Description
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 DMA controller permits packet handling for these tasks with processor time reduced to a
minimum.
