Hello,

I'm using STM32F207 with external USB-PHY in device mode.

I want to enter standby mode by SuspendCallback of USB. Because it is not possible to wakeup the STM32 by interrupt (ResumeCallback), I want to use the wakeup pin.

It is possible to use the output pin of external PHY (USB3300, signal D3) for wakeup?

Thanks,

Guenter

RM0033:

The microcontroller exits Standby mode when an external Reset (NRST pin), an IWDG

Reset, a rising edge on WKUP pin, an RTC alarm, a tamper event, or a time stamp event isdetected.
