Abstract
An automotive electronic control unit receives rewrite data wirelessly transmitted in units of a predetermined size from an external device and rewrites data stored in a nonvolatile memory based on the rewrite data. At this time, the rewrite data is communicated by switching between broadcast communication and unicast communication, or between multicast communication and unicast communication.
