Problem Fix/Workaround
None.
2. High current consumption in sleep mode
If a pending interrupt cannot wake the part up from the selected sleep mode, the current consumption will
increase during sleep when executing the SLEEP instruction directly after a SEI instruction.
Problem Fix/Workaround
Before entering sleep, interrupts not used to wake the part from the sleep mode should be disabled.
11.5 ATmega1281 rev. B
• High current consumption in sleep mode
1. High current consumption in sleep mode
If a pending interrupt cannot wake the part up from the selected sleep mode, the current consumption will
increase during sleep when executing the SLEEP instruction directly after a SEI instruction.
Problem Fix/Workaround
Before entering sleep, interrupts not used to wake the part from the sleep mode should be disabled.
11.6 ATmega1281 rev. A
• Inaccurate ADC conversion in differential mode with 200× gain
• High current consumption in sleep mode
1. Inaccurate ADC conversion in differential mode with 200× gain
With AVCC <3.6V, random conversions will be inaccurate. Typical absolute accuracy may reach 64 LSB.
Problem Fix/Workaround
None.
2. High current consumption in sleep mode
If a pending interrupt cannot wake the part up from the selected sleep mode, the current consumption will
increase during sleep when executing the SLEEP instruction directly after a SEI instruction.
Problem Fix/Workaround
Before entering sleep, interrupts not used to wake the part from the sleep mode should be disabled.
11.7 ATmega2560 rev. F
• ADC differential input amplification by 46dB (200x) not functional
1. ADC differential input amplification by 46dB (200x) not functional
Problem Fix/Workaround
None.
11.8 ATmega2560 rev. E
No known errata.
11.9 ATmega2560 rev. D
Not sampled.
