From the MM2 manual. The MM2 can wake up from pin 16 fast enough to also decode the IR remote control message. So you won't miss a pulse from this charger. Problem I see is when the charger does not output any pulse (=0) you sleep forever (unless you implement a watchdog). Jim's idea can also work with a CD4024 (if that is in your parts bin).
