Function Documentation

mtb_pmbus_status_t mtb_pmbus_get_read_zone	(	mtb_pmbus_stc_t *	inst,
		uint32_t *	zone,
		uint32_t	page
	)

Returns assigned Read Zone to this target device.

If the instance does not support pages, then the page parameter is ignored and the function returns the global zones assigned to this instance.

Note: This function is only available when MTB_PMBUS_SUPPORT_ZONE is enabled at compile time options.

Parameters

inst	The pointer to the PMBus instance structure
zone	The pointer to variable for storing the Read Zone
page	The page number for zone assignment

mtb_pmbus_status_t mtb_pmbus_get_write_zone	(	mtb_pmbus_stc_t *	inst,
		uint32_t *	zone,
		uint32_t	page
	)

Returns assigned Write Zone to this target device.

If the instance does not support pages, then the page parameter is ignored and the function returns the global zones assigned to this instance.

Note: This function is only available when MTB_PMBUS_SUPPORT_ZONE is enabled at compile time options.

Parameters

inst	The pointer to the PMBus instance structure
zone	The pointer to variable for storing the Write Zone
page	The page number for zone assignment

mtb_pmbus_status_t mtb_pmbus_get_active_zones	(	mtb_pmbus_stc_t *	inst,
		uint32_t *	zone_read,
		uint32_t *	zone_write
	)

Returns the active zones.

Note: This function is only available when MTB_PMBUS_SUPPORT_ZONE is enabled at compile time options.

Parameters

inst	The pointer to the PMBus instance structure
zone_read	The pointer to variable for storing the active Read Zone
zone_write	The pointer to variable for storing the active Write Zone

mtb_pmbus_status_t mtb_pmbus_set_default_zones	(	mtb_pmbus_stc_t *	inst,
		uint32_t	zone_read,
		uint32_t	zone_write,
		uint32_t	page
	)

Sets the default zones for the device.

Use this function to change the default zones during the initialization of the device: after mtb_pmbus_init() and before mtb_pmbus_enable().

By default the 0xFE is assigned to Read and Write Zones during initialization stage.

If instance does not support pages, then the page parameter value is ignored and zones are assigned globally for instance.

Note: This function is only available when MTB_PMBUS_SUPPORT_ZONE is enabled at compile time options.

Warning: This function does not check for invalid zone values. This is done for flexibility purposes, as there are several ranges of zone values.

Parameters

inst	The pointer to the PMBus instance structure
zone_read	The Read Zone to assign to this device
zone_write	The Write Zone to assign to this device
page	The page number for zone assignment
