I have two open-collector outputs, one from a PS2 keyboard and one from a DS3231 Real Time Clock. I am, successfully, throwing an arduino ATMEGA1884p into sleep mode with a set_sleep_mode(SLEEP_MODE_PWR_DOWN); However, I would like to raise it out of sleep mode by, either, pressing on the Ps-2 key…
