13.6 Notes on Using Interrupt Pin Selection Circuit
This section provides notes on using the interrupt pin selection circuit.
• 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 (a value other than "0b00" is
written to the SL0[1:0] bits in the EIC register of the external interrupt circuit to select a
valid edge, and "1" is written to the EIE0 bit to enable the interrupt request.), the input to
the selected pins will remain enabled so as to accept interrupts even in standby mode.
• If multiple interrupt pins are selected in the WICR register simultaneously, an input to
INT00 (ch. 0) of the external interrupt circuit is treated as "H" if a signal input to one of the
selected interrupt pins is "H" (It becomes "OR" of the signals input to the selected pins).
