Abstract

When an ECU serving as a communication node is under sleep mode, a switch portion in a transceiver connects a data transmit port of a microcomputer to a memory controller. The microcomputer sends, to the memory controller, a code write-in request for writing a code while outputting a write data that is written as the code. The data transmit port, which is to output a communication data, is commonly used in order to output the write-in request and the write data; this suppresses the increase in the number of connection lines between the microcomputer and the transceiver and the increase in the number of ports of the microcomputer.
