Abstract
An electronic control apparatus such as an ECU of a motor vehicle contains first and second microcomputers, with the first microcomputer having a substantially higher data receiving performance than the second microcomputer. Data for updating a ROM of the second microcomputer, transmitted to the first microcomputer from an external apparatus at a relatively high data rate, are temporarily stored in RAM by the first microcomputer and then transmitted to the second microcomputer at a rate which is appropriate for the receiving performance of the second microcomputer.
