RT1050: USB availability in low-speed run mode

[jayyehtw]

HI,

I am now experimenting the mechanism of  low power mode of RT1050.

I follow the reference of this document: https://www.nxp.com/docs/en/application-note/AN12094.pdf.

According to it, the USB PLL and PFDx are powered down in the low-speed run mode. 

So I am wondering if it is possible to use USB module when in low-speed run mode.

Thanks

Jay

-- No, I'm afraid it's impossible.
Have a great day,
