Universal Asynchronous Receiver-Transmitter
(UART) Port—Receive and Transmit Timing
Figure 26
The maximum baud rate is SCLK/16. As shown in
there is some latency between the generation internal UART
interrupts and the external data operations. These latencies are
negligible at the data transmission rates for the UART.
TRANSMIT
describes UART port receive and transmit operations.
