I would like my system to awaken from a sleep mode by pressing any one of two available buttons on the front. These buttons also serve as inputs when the system is awake.
Would it be possible to configure these buttons to serve this dual purpose?
My initial reaction is to run the INTx pin and the I/O pin both through the button to ground (i.e. the button is configured for pull-up pins).
Which brings me to my next question: Are interrupt pins configured as pull-up or pull-down?
Thanks in advance.
