Errata ATmega88PA
The revision letter in this section refers to the revision of the ATmega88PA device.
35.4.1
Rev. F
Analog MUX can be turned off when setting ACME bit
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 MUX'es are turned off until the ACME bit is cleared.
Problem Fix/Workaround
Clear the MUX3 bit before setting the ACME bit.
