Oscillator Calibration Register
– OSCCAL
28
ATmega16(L)
Table 10. Start-up Times for the Internal Calibrated RC Oscillator Clock Selection
Note:
• Bits 7..0 – CAL7..0: Oscillator Calibration Value
Writing the calibration byte to this address will trim the Internal Oscillator to remove pro-
cess variations from the Oscillator frequency. This is done automatically during Chip
Reset. When OSCCAL is zero, the lowest available frequency is chosen. Writing non-
zero values to this register will increase the frequency of the Internal Oscillator. Writing
$FF to the register gives the highest available frequency. The calibrated Oscillator is
used to time EEPROM and Flash access. If EEPROM or Flash is written, do not cali-
brate to more than 10% above the nominal frequency. Otherwise, the EEPROM or Flash
write may fail. Note that the Oscillator is intended for calibration to 1.0, 2.0, 4.0, or
8.0 MHz. Tuning to other values is not guaranteed, as indicated in Table 11.
