Universal Asynchronous Receiver/
Transmitter
PS013014-0107
The UART module implements the logic required to support various 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
The UART module provides the following asynchronous communication protocol-related
features and functions:
