Oscillator Tuning

The INTOSC is factory calibrated but can be adjusted

in software by writing to the OSCTUNE register

(Register 7-2).

The default value of the OSCTUNE register is ‘0’. The

value is a 6-bit two’s complement number.

When the OSCTUNE register is modified, the INTOSC

frequency will begin shifting to the new frequency. Code

execution continues during this shift. There is no

indication that the shift has occurred.
