Universal Asynchronous Receiver-Transmitter
(UART) Ports—Receive and Transmit Timing
Figure 24 describes the UART ports receive and transmit opera-
tions. The maximum baud rate is SCLK/16. As shown in
Figure 24 there is some latency between the generation of
internal UART interrupts and the external data operations.
These latencies are negligible at the data transmission rates for
the UART.
