USB_H1_PWR_CTL_WAKE

Can anyone tell me what this signal does and how it is supposed to be configured? Can I just ignore it?

I've searched the documentation and I don't see anything relevant.

Hi Nicholas

USB_XX_PWR_CTL_WAKE is an output asserted by the USB controller

whenever the USB controller and PHY wake up due to a software resume or

a USB remote wakeup. It can be used as a USB wakeup signal to the rest

of the system in all low power modes where the USB Phy stays alive.

It is active high and is active during the wake up stage of the USB (due to a

software resume or a remote USB wakeup event).

Best regards

igor
