istics” on page 242.
Changes from Rev. 1. Updated V_BOT values in Table 15 on page 38.
2486J-02/03 to
Rev. 2486K-08/03 ^{2. Updated “ADC Characteristics” on page 248.}
3. Updated “ATmega8 Typical Characteristics” on page 249.
4. Updated “Errata” on page 296.
Changes from Rev. 1. Improved the description of “Asynchronous Timer Clock – clk_ASY” on page 26.
2486I-12/02 to Rev.
2486J-02/03
2. Removed reference to the “Multipurpose Oscillator” application note and the “32 kHz
Crystal Oscillator” application note, which do not exist.
