Universal Asynchronous Receiver/
Transmitter
PS015308-0404
The UART module implements all of the logic required to support several asynchronous
communications protocols. The module also implements two separate 16-byte-deep
FIFOs for both transmission and reception. A block diagram of the UART is illustrated in
Figure 24.
