If the AW is not used for debugging, the aWire UART can be used by the user to send or receive
data with one start bit, eight data bits, no parity bits, and one stop bit. This can be controlled
through the aWire UART user interface.
This chapter only describes the aWire UART user interface. For a description of the aWire
Debug Interface, please see the Programming and Debugging chapter.
Asynchronous receiver or transmitter when the aWire system is not used for debugging.
One- or two-pin operation supported.
