Operation: \n1. MCU will boot up in extremely low power mode (LPM4) upon battery insertion. EN is high/floating?\n2. Once PREV or NEXT (acting as PWRON) receives a debounced HIGH from the switch between the pin and VCC, the MCU will switch into LPM1 and display either flashing d6 \n(first boot, dX selection of 4, 6, 8, 10, 12, 20, or 100) OR whatever it displayed last time, in which case, a NEXT is required to get it to the flashing d6. \n3. NEXT finishes dX selection, moving on to Y(dX) selection, starting from 1dX and going up to 99 (a moving left-right animation will have to be done for d12-d100). Y will be 1 by default and not flash. \nShort NEXT proceeds, short PREV back. Long press either to enter Y selection where Y flashes. NEXT up, PREV down. Long press again to exit. If the die is d12-d100, the animation will stop so that Y is \ndisplayed flashing for a 5 second period when either NEXT or PREV has been long-pressed. \n4. NEXT goes to number generation. The numbers that the MCU reads from the TEMP ADC + TIMER (so it overflows) are fed continuously through the display.\n5. After a 1 sec delay or a NEXT, the result will be displayed and flash for 5 seconds. Pressing PREV here will loop back to 4, and reroll the same dice. \n6. After 2 minutes of inactivity in any stage, the display will shut down, and the device will enter LPM4.
