I
Receive Data. This signal is the receiver input for the UART and IrDA.
Clear To Send signal from the receiving device that ready to receive
data.
TXDE
O
Driver Enable. This signal allows automatic control of external RS-485
drivers. The DE signal may be used to ensure an external RS-485 driver
is enabled when data is transmitted by the UART.
