• P74/AN4
The pin function is switched as shown below according to the combination of the SCANE bit
in ADCR and the CH2 to CH0 bits in ADCSR of the A/D converter. Do not set these bits to
other values than those shown in the following table.
SCANE 0 1
CH2 to CH0 B'100 Other than B'100 B'100 to B'111 B'000 to B'011
Pin function AN4 input pin P74 input pin AN4 input pin P74 input pin
• P73/AN3
The pin function is switched as shown below according to the combination of the SCANE and
