Fix/Workaround:
There is no fix for this problem.
3 –
Increased AC offset on low input voltages
Analog comparator may have an offset greater than 40 mV on low input
voltages (Vin < 0.5V) when VCC > 3.6V.
Fix/Workaround:
Avoid using low input voltages to the analog comparator when VCC is
greater than 3.6V

38.3.4 Rev. E
1 – Analog MUX can be turned off when setting ACME bit
If the ACME (Analog Comparator Multiplexer Enabled) bit in ADCSRB is set
while MUX3 in ADMUX is '1' (ADMUX[3:0]=1xxx), all MUXes are turned off
until the ACME bit is cleared.
Fix/Workaround:
Clear the MUX3 bit before setting the ACME bit.
