#include <zephyr/drivers/misc/interconn/renesas_elc/renesas_elc.h>

Enable the operation of the Event Link Controller.

This function enables the ELC so that it can process events.

Parameters

dev	Event Link Controller device.

Returns: 0 if successful.; A negative errno code on failure.

◆ renesas_elc_link_break()

int renesas_elc_link_break	(	const struct device *	dev,
		uint32_t	peripheral )

#include <zephyr/drivers/misc/interconn/renesas_elc/renesas_elc.h>

Break an event link.

This function breaks an existing event link for the given peripheral.

Parameters

dev	Event Link Controller device.
peripheral	Peripheral ID whose link is to be broken.

Returns: 0 if successful.; A negative errno code on failure.

◆ renesas_elc_link_set()

int renesas_elc_link_set	(	const struct device *	dev,
		uint32_t	peripheral,
		uint32_t	event )

#include <zephyr/drivers/misc/interconn/renesas_elc/renesas_elc.h>

Create a single event link.

This function configures an event link by associating a peripheral with a specific event signal.

Parameters

dev	Event Link Controller device.
peripheral	Peripheral ID to be linked to the event signal.
event	Event signal ID to be associated with the peripheral.

Returns: 0 if successful.; A negative errno code on failure.
