This pin is multiplexed between LCD Bridge, UART, GPIO, and I2S3.
When used by UART, it is the receive data input UART_RXD.
Mux control via the PPMODE bits in the EBSR. The IPD resistor on this pin can be
enabled or disabled via the PDINHIBR3 register.
This pin is multiplexed between LCD Bridge, UART, GPIO, and I2S3.
In UART mode, it is the transmit data output UART_TXD.
Mux control via the PPMODE bits in the EBSR. The IPD resistor on this pin can be
enabled or disabled via the PDINHIBR3 register.
This pin is multiplexed between LCD Bridge, UART, GPIO, and I2S3.
In UART mode, it is the clear to send input UART_CTS.
Mux control via the PPMODE bits in the EBSR. The IPD resistor on this pin can be
enabled or disabled via the PDINHIBR3 register.
This pin is multiplexed between LCD Bridge, UART, GPIO, and I2S3.
In UART mode, it is the ready to send output UART_RTS.
Mux control via the PPMODE bits in the EBSR. The IPD resistor on this pin can be
enabled or disabled via the PDINHIBR3 register.

I = Input, O = Output, Z = High impedance, S = Supply voltage, GND = Ground, A = Analog signal, BH = Bus Holder
Input pins of type I, I/O, and I/O/Z are required to be driven at all times. To achieve the lowest power, these pins must not be allowed to
float. When they are configured as input or high-impedance state, and not driven to a known state, they may cause an excessive IO-
supply current. Prevent this current by externally terminating it or enabling IPD/IPU, if applicable.
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 3.8.1 , Pullup/Pulldown Resistors .
