Abstract

PURPOSE:To facilitate the selection of an operating mode by a method wherein a circuit module constituting clock signal distributing block is provided with a clock signal type discriminating means and an operating mode indicating signal outputting means activated by the output of said discriminating means and several circuit module constituting functional blocks are respectively provided with mode indicating means. CONSTITUTION:A clock signal distributing block 2 and other functional blocks 3-8 are mounted on a board 1 and each of the functional blocks 3-8 is connected to the block 2 by wirings 10-10'''. Provided within the block 2 are a discriminating circuit 22 consisting of a buffer circuit BUF, a differential circuit DIF, rectifying and smoothin circuit SM, and a comparing circuit COMP, and a distributing circuit 21. Inputted clock signals are supplied as they stand to the functional blocks 3-8 through the circuit 21 and the wirings 10-10'''. Also, each functional block 3-8 contains a mode indicating signal detecting circuit 31- 81 that is similar to the discriminating circuit 22. The circuits within the module operate on a normal mode when the functional blocks detect signals indicating a normal mode operation.
