GPIO_7 Function Select Bit.
Cleared to 0 by user code to configure the GPIO_6 pin as a general-purpose I/O (GPIO) pin.
Set to 1 by user code to configure the GPIO_6 pin as TxD, transmit data for UART serial port.
Cleared to 0 by user code to configure the GPIO_5 pin as a general-purpose I/O (GPIO) pin.
Set to 1 by user code to configure the GPIO_5 pin as RxD, receive data for UART serial port.
Cleared to 0 by user code to route the LIN transmit data to an internal general-purpose I/O (GPIO_12) pad that can then be
written via the GP2DAT MMR.
Set to 1 by user code to route the UART TxD (transmit data) to the LIN data pin. This configuration is used in LIN mode.
Cleared to 0 by user code to internally disable the LIN input data path. In this configuration, GPIO_11 is used to support
diagnostic readback on all external high voltage I/O pins (see HVCFG1[2:0]).
Set to 1 by user code to route input data from the LIN interface to both the LIN hardware timing/synchronization logic and to
the UART RxD (receive data). This mode must be configured by user code when using LIN.

Cleared to 0 by user code to configure the GPIO_7 pin as a general-purpose I/O (GPIO) pin.
Set to 1 by user code to route data driven into the GPIO_7 pin through the on-chip LIN transceiver to be output at the LIN
pin. This mode can be used to drive the LIN transceiver interface as a standalone component without any interaction from
MCU or UART.
