Function Documentation

mtb_pmbus_smbalert_config_mode()

void mtb_pmbus_smbalert_config_mode	(	mtb_pmbus_stc_t *	inst,
		mtb_pmbus_smbalert_mode_t	mode
	)

Sets the mode for SMBALERT pin.

Note

This function is only available when MTB_PMBUS_SUPPORT_SMBALERT is enabled at compile time options.

Parameters

inst	The pointer to the PMBus instance structure
mode	The selected mode, mtb_pmbus_smbalert_mode_t

mtb_pmbus_smbalert_set_signal()

void mtb_pmbus_smbalert_set_signal

(

mtb_pmbus_stc_t *

inst

)

Set low level for SMBALERT pin.

Once the SMBALERT signal sets to 0, the Middleware starts to response on Alert Response Address.

This function does nothing if mtb_pmbus_stc_config_t::enable_smbalert is set to NULL.

Note

This function is only available when MTB_PMBUS_SUPPORT_SMBALERT is enabled at compile time options.

Parameters

inst	The pointer to the PMBus instance structure

mtb_pmbus_smbalert_clear_signal()

void mtb_pmbus_smbalert_clear_signal

(

mtb_pmbus_stc_t *

inst

)

Set hign level for SMBALERT pin.

This function does nothing if mtb_pmbus_stc_config_t::enable_smbalert is set to NULL.

The middleware stops response on Alert Response Address once this function is called. If the SMBALERT mode is MTB_PMBUS_SMBALERT_MODE_AUTO, the middleware automatic clears the SMBALERT signal, otherwise clear the signal manually in mtb_pmbus_handle_events_t callback when MTB_PMBUS_ALERT_RESPONSE_ADDR_EVENT is triggered.

Note

This function is only available when MTB_PMBUS_SUPPORT_SMBALERT is enabled at compile time options.

Parameters

inst	The pointer to the PMBus instance structure
