1. An electronic device comprising:
a master; and
a plurality of slaves to which a plurality of mutually different identifiers is, respectively, assigned, wherein each slave of the plurality of slaves:
transmits, to the master, a first signal representing a bit sequence that contains a bit representing whether an interrupt is occurring in the slave, and changes a position of the bit based on an identifier, among the plurality of mutually different identifiers, assigned to the slave, and
has a register configured to output the first signal, and causes the master to identify the slave, as one of the plurality of slaves in which the interrupt is occurring, by changing the position of the bit in the bit sequence of the first signal that is output from the register.
