Universal Asynchronous Receiver-Transmitter
(UART) Ports—Receive and Transmit Timing
The UART ports have a maximum baud rate of SCLK/16. There
is some latency between the generation of internal UART inter-
rupts and the external data operations. These latencies are
negligible at the data transmission rates for the UART. For more
information, see the ADSP-BF54x Blackfin Processor Hardware
Reference.
