44.4 Functional description
This section provides a complete functional description of the UART block.
The UART allows full duplex, asynchronous, NRZ serial communication between the
CPU and remote devices, including other CPUs. The UART transmitter and receiver
operate independently, although they use the same baud rate generator. The CPU
monitors the status of the UART, writes the data to be transmitted, and processes
received data.
