PIC16C505

4.5 OSCCAL Register

The Oscillator Calibration (OSCCAL) register is used to

calibrate the internal 4 MHz oscillator. It contains six

bits for calibration

Note:

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.

After you move in the calibration constant, do not

change the value. See Section 7.2.5
