Prevention of USB Suspend Mode in PN7462

[Bhavin-Dhulkotiya]

We want to exercise the Suspend Mode on PN7462 EVK on the phExCcid SDK example. The EVK is connected to the Laptop through a micro USB cable. We configured the macro as PH_EXNFCCCID_USB_IF_USB_SUSPEND_RESUME_FTR 1 and run the code in debug mode.

I am getting prevention reason as E_HOSTCOMM_ONGOING though there is no ongoing communication with the Host. Why is there prevention? Or could you share a proven example of Suspend Mode?

@KellyLi Thanks for pointing to the right document.

The PH_EXCCID_USB_IF_USB_REMOTE_WAKEUP_FTR macro also needs to be set as 1.
