<p>PROBLEM TO BE SOLVED: To connect an external device to a microcomputer without providing any interface circuit outside a microcomputer. SOLUTION: This microcomputer (10) is provided with a timing generation memory block (25). Thus when the operations of external devices (26, 27) arranged outside the microcomputer (10) are controlled by a bus master, the generating timing of an external device control signal to be supplied to the external devices can be set into a programmable state according to the external devices, and also the external device control signal generating timing information can be written in the timing generation memory block is made possible by a writing controlling means (17) so that it is made to deal with the external devices.</p> |
