system_pinmux_config Struct Reference

Port pin configuration structure.

Configuration structure for a port pin instance. This structure should be initialized by the system_pinmux_get_config_defaults() function before being modified by the user application.

enum system_pinmux_pin_pull system_pinmux_config::input_pull

Logic level pull of the input buffer.

uint8_t system_pinmux_config::mux_position

MUX index of the peripheral that should control the pin, if peripheral control is desired.

For GPIO use, this should be set to SYSTEM_PINMUX_GPIO.

bool system_pinmux_config::powersave

Enable lowest possible powerstate on the pin.

Note

All other configurations will be ignored, the pin will be disabled.
