Device is ATTINY_13.  I don't see anything in the data sheet about this (looking in the wrong places?).  I need a pullup (internal or external) on an INT pin for wakeup.  Thanks.

The port registers are not changed by the cpu entering sleep mode, so they will stay in what ever configuration they were in when the cpu enters sleep (cpu clock stopped),

port bits will be high/low, and pullup enabled/disabled as before.  Reset as pointed out above will change their state back to initial values.......

 

Have fun.
