Register Description
Oscillator Calibration Register
– OSCCAL

ATtiny11/12
• 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. 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 access. If EEPROM is
written, do not calibrate to more than 10% above the nominal frequency. Otherwise, the
EEPROM write may fail. Table 4 shows the range for OSCCAL. Note that the oscillator
is intended for calibration to 1.2 MHz, thus tuning to other values is not guaranteed.
