Bits 3:0 – OSCCAL16MTCAL[3:0]: OSC16 Temperature Calibration

OSC16 Temperature Calibration

These bits contain factory temperature calibration values for the internal 16 MHz oscillator. If the OSCCFG fuse is configured to run the device at 16 MHz, this byte is automatically written into the OSC20MCALIBB register during Reset to ensure correct frequency of the calibrated RC Oscillator.
