Abstract

PURPOSE: To always read an accurate data value by continuously outputting a prescribed write detection signal to an external part while an incorporated register writes the data.
CONSTITUTION: When an instruction writing data into the register 1 is executed, an instruction execution circuit 2 inputs the data to the register 1 through an internal bus 101 and a register write signal 103 is outputted and prescribed data is set in the register 1. The register write signal 103 from the circuit 2 is inputted to the register 1 and a write detection circuit 3, and the write detection signal 105 is continuously outputted to the external part until writing is terminated. Reading is executed in a time zone when 105 is not outputted and the accurate value of the register 1 is read to the external part.
