UART0
This pin is multiplexed between UART0 (Data) and GPIO.
When used by UART0 this pin is the receive data input URXD0.
This pin is multiplexed between UART0 (Data) and GPIO.
In UART0 mode, this pin is the transmit data output UTXD0.
This pin is multiplexed between the UART0 (Flow Control) and GPIO.
In UART0 mode, this pin is the clear to send input UCTS0.
This pin is multiplexed between the UART0 (Flow Control), PWM0,
and GPIO.
In UART0 mode, this pin is the ready to send output URTS0.
(1) I = Input, O = Output, Z = High impedance, S = Supply voltage, GND = Ground, A = Analog signal
(2) IPD = Internal pulldown, IPU = Internal pullup. For more detailed information on pullup/pulldown resistors and situations where external
pullup/pulldown resistors are required, see Section 3.9.1, Pullup/Pulldown Resistors.
(3) Specifies the operating I/O supply voltage for each signal
