OSCCAL Register  
The Oscillator Calibration (OSCCAL) register is used to  
calibrate the internal precision 4 MHz oscillator. It  
contains seven bits for calibration.  
Note:  
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.  
After you move in the calibration constant, do not  
change the value. See Section 9.2.2 “Internal 4 MHz  
Oscillator”.
