Function Documentation

Enable the input function of a Group of Pins.

Enable or disable the input function of one or more pins of GPIO. Disabling the input function of pins decreases the power usage of the MCU.

Parameters

[in]	gpios	Pin identifiers GPIO Pin Identifiers If multiple pins are to be changed, use bitwise OR '\|' to separate them.
[in]	en	True to enable input function.

Definition at line 95 of file syscon.c.

Enable the internal pull-up of a Group of Pins.

Enable or disable the internal pull-up of one or more pins of GPIO.

Parameters

[in]	gpios	Pin identifiers GPIO Pin Identifiers If multiple pins are to be changed, use bitwise OR '\|' to separate them.
[in]	en	True to enable pull-up, false to disable.

Definition at line 75 of file syscon.c.

Select the alternative function of a Group of Pins.

Select the alternative function of one or more pins of GPIO.

Parameters

[in]	gpios	Pin identifiers GPIO Pin Identifiers If multiple pins are to be changed, use bitwise OR '\|' to separate them.
[in]	af_en	Whether alternative function is selected

Definition at line 43 of file syscon.c.

void syscon_sel_swd ( bool en )

Select the SWD function of GPIO 1/2.

Enable or disable the SWD debugging port at GPIO 1/2. When SWD debugging port is enabled, GPIO and AF of the SWD pins will be both unavailable.

Parameters

[in] en True to enable SWD.
