High current consumption in sleep mode
With AVCC < 3.6V, random conversions will be inaccurate. Typical absolute accu-
racy may reach 64 LSB.
Problem Fix/Workaround
None
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 instruc-
tion 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.
