Universal Asynchronous Receiver-Transmitter (UART)
Port—Receive and Transmit Timing
Figure 17
The maximum baud rate is SCLK/16. As shown in
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.
