4.5
The Oscillator Calibration (OSCCAL) register is used to
calibrate the internal 4 MHz oscillator. It contains six
bits for calibration
After you move in the calibration constant, do not
change the value. See Section 7.2.5

OSCCAL Register
Please note that 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 repro-
grammed correctly later.
