PRODUCTION DATA
If at any time the voltage on the FB_BK pin falls lower than the VBK_UVLO threshold, a buck UV fault is recognized - MCF8316C-Q1 continues to attempt regulating the FB_BK voltage to set value. Since internal circuitry in MCF8316C-Q1 is powered through the buck regulator, MCF8316C-Q1 may go into reset state if FB_BK voltage drops low enough to trigger UV on the internal circuits.
