2486J-02/03 to
Rev. 2486K-08/03
2. Updated “ADC Characteristics” on page 241.
3. Updated “ATmega8 Typical Characteristics – TA = -40°C to 85°C” on page 244.
4. Updated “Errata” on page 318.
Changes from Rev. 1. Improved the description of “Asynchronous Timer Clock – clkASY” on page 26.
2486I-12/02 to Rev.
2486J-02/03
2. Removed reference to the “Multipurpose Oscillator” application note and the “32kHz
Crystal Oscillator” application note, which do not exist.
