<p>PURPOSE:To diversify the start addresses in a reset state by starting the processes at the different addresses of a machine word instruction program according to the combination of plural signals applied to plural reset terminals. CONSTITUTION:The reset signal terminals 108-1 and 108-2 are connected to a microsequencer 103 via the signal lines 109-1 and 109-2. At the same time, the lines 109-1 and 109-2 are inputted to an OR gate 110 and the output 111 of the gate 110 is turned into an internal reset signal of the processor 101. Then the processes are started at the different addresses of a machine word program according to the combination of plural signals applied to both terminals 108-1 and 108-2. As a result, a microprocessor can be initialized into a desired state.</p> |
