Note:
The input signals to the peripheral pins do not generate an external interrupt even when
"1" is written to these bits if the INT00 (ch. 0) of the external interrupt circuit is disabled.
Do not modify the values of these bits while the INT00 (ch. 0) of the external interrupt
circuit is enabled. If modified, the external interrupt circuit may detect a valid edge,
depending on the pin input level.
If multiple interrupt pins are selected in the WICR register simultaneously and the
operation of INT00 (ch. 0) of the external interrupt circuit is enabled (the values other than
"0b00" are written to the SL0[1:0] bits in the EIC register of the external interrupt circuit.),
the selected pins will remain enabled to perform input so as to accept interrupts even in
standby mode.
