The Oscillator Calibration (OSCCAL) register is used to
calibrate the internal precision 4 MHz oscillator. It
contains seven bits for calibration

OSCCAL Register
Erasing the device will also erase the pre-
programmed internal calibration value for
the internal oscillator. The calibration
value must be read prior to erasing the
part so it can be reprogrammed correctly
later.
