With AVCC < 3.6V, random conversions will be inaccurate. Typical absolute accuracy 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 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.
