The ATtiny13 automatically writes its stored calibration byte into OSCCAL at startup -- right? Do the other current AVRs do the same thing?

This is something that has been developed over time, so while new devices have it, some older don't.

This is intended to be my personal opinion which may,

There are three levels of support:
- Chips that do nothing, and need you to calibrate them.
- Chips that have calibration constants in "extra memory", and that auto-load the lowest-speed cal constant on powerup. Pain in the ass, impossible to use for mass-production.
- Chips that automatically load the right factory cal constant based on which internal osc speed you selected.
