GPIO pin mode

This describes the pin direction when it’s a GPIO pin. It does not describe the direction for other I/O, like LPI2C or LPUART.

In order to set alternate functions such as LPI2C or LPUART, you will need to use iomuxc enable_sw_mux_ctl_pad_gpio with the specific MUX_MODE according to the reference manual (Chapter 11). For the gpio mode, input or output we set the GDIR pin accordingly ¹
