STM32H7x: Register PWR_CR3, Bit USB33DEN

Hello Community,

 

in the STM32H7 power control i can find the bit USB33DEN in the
register PWR_CR3. As the reference manual explains with this bit
i can enable/disable the VDD33USB supply voltage level detector.

 

Can anybody explain me what functionality is behind this bit?
What did the VDD33USB supply voltage level detector have?
Did the VDD33USB supply voltage level detector generate an enable
signal to the USB transceiver?

 

Best Regards
Torsten
