Wake on VBUS connected but not disconnectedW

[Constantin]

Hi,

we are developing a device which should go to system off on receival of a command either via USB or BLE. If the device is connected via USB and is put into sleep it wakes up if the cable is disconnected. But it should stay in system off. Any idea why this happens and how to avoid it.

Kind regards,

C.W.

When analyzing the RESETREAS register after wakeup the following can be found

C

RW

SREQ

Reset from soft reset detected

NotDetected

0

Not detected

1

and

G

RW

DIF

Reset due to wake up from System OFF mode when wakeup is triggered from entering into debug interface mode

NotDetected

I am not sure what it means and appreciate any help.

Kind regards, C.W.
