O General-Purpose Timer Outputs.
I General-Purpose Timer Input. This signal is used as the capture, gating
and counter inputs.
UART Controller
TXD
RXD
CTS
TXDE
O Transmit Data. This signal is the transmit output from the UART and
IrDA.
I Receive Data. This signal is the receiver input for the UART and IrDA.
I Clear To Send signal from the receiving device that ready to receive
data.
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.
