2490R–AVR–02/2013
ATmega64(L)
10. Updated “TWI – Two-wire Serial Interface” on page 198.
More details regarding use of the TWI Power-down operation and using the TWI as master
with low TWBRR values are added into the data sheet. Added the note at the end of the “Bit
Rate Generator Unit” on page 204. Added the description at the end of “Address Match Unit”
on page 205.
11. Updated Description of OSCCAL Calibration Byte.
In the data sheet, it was not explained how to take advantage of the calibration bytes for 2,
4, and 8 MHz Oscillator selections. This is now added in the following sections:
Improved description of “OSCCAL – Oscillator Calibration Register(1)” on page 43 and “Cal-
ibration Byte” on page 293.
12. When using external clock there are some limitations regards to change of frequency.
This is descried in “External Clock” on page 44 and Table 131 on page 327.
13. Added a sub section regarding OCD-system and power consumption in the section
“Minimizing Power Consumption” on page 49.
14. Corrected typo (WGM-bit setting) for:
– “Fast PWM Mode” on page 99 (Timer/Counter0).
– “Phase Correct PWM Mode” on page 101 (Timer/Counter0).
– “Fast PWM Mode” on page 152 (Timer/Counter2).
– “Phase Correct PWM Mode” on page 153 (Timer/Counter2).
15. Corrected Table 81 on page 192 (USART).
16. Corrected Table 102 on page 262 (Boundary-Scan)
