IPC: G06F9/42
Filed: 1983-09-09
Abstract: PURPOSE:To change easily a control program by setting optionally the contents of a jumping vector address owing to the interruption of a CPU with no exchange of an ROM. CONSTITUTION:When an interruption signal I is sent to a CPU6, the CPU6 reads the data on a vector address corresponding to the interruption.

A data line B is set at a low level only when both inputs of said information and logical arithmetic are kept at a low level, respectively. Therefore the CPU6 can obtain information from the line B. The output of the circuit 9 serves as an open collector, therefore exerts no evil effect on the line B unless the output C of the decoder 7 is set at a low level.

The resistance elements are alternately arranged adjacent to resistors 602 and 603, and the change components in the uneven resistance values are made equal with components in change in the resistance values of the resistors 602 and 603, by a change in the magnitude of the stress in mold in the short-side direction of the chip 601.  As a result, the shift of a detected coltage before and after a treatment of the chip due to the stress of the stress in molding can be inhibited.
