PIC10F220/222

4.6 OSCCAL Register

The Oscillator Calibration (OSCCAL) register is used to

calibrate the internal precision 4/8 MHz oscillator. It

contains seven bits for calibration

After you move in the calibration constant, do not

change the value. See Section 8.2.2 “Internal 4/8 MHz

Oscillator”.

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.
