Abstract

There is a need to provide a microcomputer capable of eliminating an external terminal for endian selection. Flash memory includes a user boot area for storing a program executed in user boot mode and corresponding endian information and a user area for storing a program executed in user mode and corresponding endian information. A data transfer circuit reads endian information stored in the user boot area or the user area in accordance with operation mode and supplies the endian information to a CPU before reset release of the CPU. Accordingly, an external terminal for endian selection can be eliminated.
