• P71/ExIRQ1/AN1
The pin function is switched as shown below according to the combination of the CH2 to CH0
bits in ADCSR of the A/D converter, the SCANE and SCANS bits in ADCR, and the ISS1 bit
in ISSR of the interrupt controller. Do not set these bits to other values than those shown in the
following table.
