<p>PURPOSE:To make resetting into selectivity by controlling whether or not a resetting signal is supplied for an internal function block. CONSTITUTION:A semiconductor integrated circuit 1 is composed of six function blocks 2 to 7, resetting control circuits 12 to 17 1:1 corresponding to these function blocks and a control circuit 8. A resetting signal RS inputted from an external part is supplied to all resetting control circuits 12 to 17, and the said resetting control circuits 12 to 17 respectively determines whether or not the resetting signal RS is outputted to the corresponding function blocks 2 to 7 by a control signal from the control circuit 8. Thus, the control circuit 8 stores the resetting control circuits 12 to 17 to receive the resetting signal RS beforehand and is determined based on this. The storing is executed by designating from an external part or patterning the integrated circuit and to forth.</p> |
