Long button sleep/wakeup

[Sejl]

Hi!

I would like to use long button press to send device into sleep mode (using BSP module). Since button is tied to ground, when device goes to sleep mode, and when I release button, there is transition on IO pin, and device goes back from sleep. How can I prevent this?

Thank you!

Yes, that is an option, but as in original post my pcb is already layed out so... Thank you anyway.

Again, let me comment on myself :)

If I'm already setting flag for a device to shutdown, I can turn off everything in this procedure, and then just shut down processor on button release. Customer will see that device is apparently turned off when shutdown flag has been set, and will release button...
