UART serial data input to High-Speed UART Pins.
Should be pulled low through a 10-KΩ resistor when not being utilized in the
system.
UART serial data output. The TXD signal is set to the MARKING (logic 1) state
upon a reset operation. High-Speed Serial UART Pins.
UART CLEAR-TO-SEND input to High-Speed UART Pins.
When logic 0, this pin indicates that the modem or data set connected to the
UART interface of the processor is ready to exchange data. The CTS_N signal is
a modem status input whose condition can be tested by the processor.
Should be pulled high through a 10-KΩ resistor when not being utilized in the
system.
UART REQUEST-TO-SEND output:
When logic 0, this informs the modem or the data set connected to the UART
interface of the processor that the UART is ready to exchange data. A reset sets
the request to send signal to logic 1.
LOOP-mode operation holds this signal in its inactive state (logic 1). High-Speed
UART Pins.
UART serial data input.
Should be pulled low through a 10-KΩ resistor when not being utilized in the
system.
UART serial data output. The TXD signal is set to the MARKING (logic 1) state
upon a Reset operation. Console UART Pins.
UART CLEAR-TO-SEND input to Console UART pins.
When logic 0, this pin indicates that the modem or data set connected to the
UART interface of the processor is ready to exchange data. The CTS_N signal is
a modem status input whose condition can be tested by the processor.
