Errata 8.1 Errata ATmega48A The revision letter in this section refers to the revision of the ATmega48A device. 8.1.1 Rev. D • 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. 8.2 Errata ATmega48PA The revision letter in this section refers to the revision of the ATmega48PA device. 8.2.1 Rev. D • Analog MUX can be turned off when setting ACME bit 1.
