The package wasn't at my entrance too, it was just on the sidewalk 😕
Fwiw, this is the only time the UPS driver has left the package in that spot. Normally it's right next to the front door.
If you have a memory-mapped peripheral where there's a readonly register, I could see it being const volatile.
If you have a Dremel, I bet you could take out the center bit and use a regular slotted screwdriver.
