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.
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.
The 32 kHz oscillator does not work as system clock. The 32 kHz oscillator used as asyn-
chronous timer is inaccurate.
Problem Fix/ Workaround
None.
