• P72/ExIRQ2/AN2
The port 7 function changes as shown in the following table, depending on the combination of
the SCAN bit and the CH2 to CH0 bits of ADCSR of the A/D converter and the ISS2 bit of
ISSR of the interrupt controller. Do not set these bits to other values than those shown in the
following table.
