LM3880: LM3880 power off sequence

Part Number: LM3880

Hi team,

Could you tell me about the operation to turn off the power while the IC is operating.

In the following circuit diagram, what kind of motion does FLAG move when VCC is slowly set to 0 V?

First, FLAG 3 is turned off, then FLAG 2 is turned off, and finally, FLAG 1 is turned off?

Thanks.
