How to wake-up/resume after calling SetSystemPowerState

Hi,

We are currently using WINCE 7 and VS 2008. Our processor is an iMX53.

 

We are currently changing the state of our device to suspend using SetSystemPowerState(NULL, POWER_STATE_SUSPEND, POWER_FORCE) so we can save power when the system is not acquiring any readings. The problem is that after suspending the device using SetSystemPowerState in our application, we are not able to wake it up with a touch in screen, home key or interrupt signal. How we can set a GPIO/interrupt as a wake-up source or configure the i.MX53 to wake of on an interrupt event (E.X. touch screen)? Do we have to modify the registers?

 

Thanks,

MLopez
