Changes from Rev.
2486I-12/02 to Rev.
2486J-02/03
1. Improved the description of “Asynchronous Timer Clock – clk
ASY
” on page 24.
2. Removed reference to the “Multipurpose Oscillator” application note and the
“32 kHz Crystal Oscillator” application note, which do not exist.
3. Corrected OCn waveforms in Figure 38 on page 88.
4. Various minor Timer 1 corrections.
5. Various minor TWI corrections.
6. Added note under “Filling the Temporary Buffer (Page Loading)” on page 212
about writing to the EEPROM during an SPM Page load.
7. Removed ADHSM completely.
8. Added section “EEPROM Write during Power-down Sleep Mode” on page 21.
9. Removed XTAL1 and XTAL2 description on page 5 because they were already
described as part of “Port B (PB7..PB0) XTAL1/ XTAL2/TOSC1/TOSC2” on
page 5.
10. Improved the table under “SPI Timing Characteristics” on page 240 and
removed the table under “SPI Serial Programming Characteristics” on page
235.
11. Corrected PC6 in “Alternate Functions of Port C” on page 59.
12. Corrected PB6 and PB7 in “Alternate Functions of Port B” on page 56.
13. Corrected 230.4 Mbps to 230.4 kbps under “Examples of Baud Rate Setting”
on page 155.
14. Added information about PWM symmetry for Timer 2 in “Phase Correct PWM
Mode” on page 111.
15. Added thick lines around accessible registers in Figure 76 on page 165.
16. Changed “will be ignored” to “must be written to zero” for unused Z-pointer
bits under “Performing a Page Write” on page 212.
17. Added note for RSTDISBL Fuse in Table 87 on page 219.
18. Updated drawings in “Packaging Information” on page 13.
