inlinestatic

Disables callback.

Disables the callback function registered by the ac_register_callback, and the callback will not be called from the interrupt routine. The function will also disable the appropriate interrupts.

Parameters

[in]	module	Pointer to AC software instance struct
[in]	callback_type	Callback type given by an enum

static void ac_enable_callback	(	struct ac_module *const	module,
		const enum ac_callback	callback_type
	)

inlinestatic

Enables callback.

Enables the callback function registered by the ac_register_callback. The callback function will be called from the interrupt handler when the conditions for the callback type are met. This function will also enable the appropriate interrupts.

Parameters

[in]	module	Pointer to AC software instance struct
[in]	callback_type	Callback type given by an enum

enum status_code ac_register_callback	(	struct ac_module *const	module,
		ac_callback_t	callback_func,
		const enum ac_callback	callback_type
	)

Registers a callback.

Registers a callback function which is implemented by the user.

Note: The callback must be enabled by ac_enable_callback, in order for the interrupt handler to call it when the conditions for the callback type is met.

Parameters

[in]	module	Pointer to software instance struct
[in]	callback_func	Pointer to callback function
[in]	callback_type	Callback type given by an enum

Return values

STATUS_OK The function exited successfully

References Assert, and STATUS_OK.

enum status_code ac_unregister_callback	(	struct ac_module *const	module,
		const enum ac_callback	callback_type
	)

Unregisters a callback.

Unregisters a callback function implemented by the user.

Parameters

[in]	module	Pointer to AC software instance struct
[in]	callback_type	Callback type given by an enum

Return values

STATUS_OK The function exited successfully

References Assert, and STATUS_OK.
