<p>PURPOSE:To prevent a package to be controlled from malfunctioning even when a control package is inserted or extracted as to the subject data processor including the control package and the package to be controlled which inputs control information from the control package. CONSTITUTION:When a source voltage detecting circuit 200 detects the source voltage of the control package 10 dropping below a specific value, the current control information 1 from the control package 10 is held in a latch circuit 100. Consequently, even if the control package 10 is inserted or removed, the control information 1 is held in the latch circuit 100, so malfunction in the package 20 to be controlled is prevented.</p> |
