<p>A microcomputer (101) which can freely select the location of actuating a program after the microcomputer (101) is reset; and electronic equipment provided therewith. The microcomputer (101) incorporates a CPU (102) which controls the readout, analysis, and execution of instructions with respect to the electronic equipment, a given switching terminal (BTA3), and a circuit (150) which switches the boot address to be read out first by the CPU (102) after the microcomputer (101) is reset based on the state of the switching terminal (BTA3). When the terminal (BTA3) is on the side of '1', a resetting program by which a trap vector 0x0080000 is generated and stored in an internal ROM (112) is actuated. When the terminal (BTA3) is on the side of '0', another resetting program by which a trap vector 0x00C00000 is generated and stored in an external ROM (116), is actuated. Therefore, the microcomputer (101) can be actuated, for example, from the external ROM (116) at the time of product development, etc., and from the internal ROM (112) at the time of mass production.</p> |
