• P75/ExIRQ5/AN5
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, and the ISS5 bit in ISSR
of the interrupt controller. Do not set these bits to other values than those shown in the
following table.
SCANE 0 1
