AVR-Chat

I'm new to AVR so I can't get into specifics.  In general, to avoid  
using an external crystal a timebase for the chip can be generated by  
an internal RC.  These types of RC are not very precise so the chip  
maker can do one of two things.  1.  Make them more precise by  
individually trimming the R using a laser on a chip by chip basis to  
improve accuracy.  2. measure just how imprecise the RC is on a chip  
by chip basis and store a correction factor that is applied to get  
the clock.  That correction factor is stored in the oscillator  
calibration register.

I hope that's what you were looking for.
