I have question about of UCS Module Fail-Safe Operation.
We are facing the issue of increased power consumption due to UCS fail-safe operation.
We are using XT1 operation ins LF mode, when a clock failure occurs in XT1, the fail-safe function switches the clock source, and as a result only MSP430 has a current increase of about 4μA.
Although the oscillator failure has been removed and the DCOFFG, XT1LFOFFG, and OFIFG registers have been checked to confirm that the failure has been removed, a current increase of about 1μA can be seen compared to before the occurrence of the oscillator failure.
We predicted that the current consumption would be equal since the clock resources would return to their pre-fault state when the MSP430 recovers from the oscillator failure. Wwhat is the reason for the 1A current increase?
