<p>PURPOSE:To control the time up to execution by a program by selecting hardware or software according to the output values of a CERD flag (reset detector flag) and a CERE flag (reset enable flag), and determining the timing of initialization. CONSTITUTION:An initializing function block 2 initializes an internal circuit (not shown in figure) with an external initialization signal 101. The CERD flag (reset detector flag) 4 is used to select programmed control or hardware control as initialization timing control over said internal circuit based upon the initialization signal 101. The CERE flag (reset enable flag) 5 is used to control the initialization timing by the program with the output timing of a state value. A timer 3 generates an initialization timing pulse whose timing is controlled with the CERD flag 4 and CERD 5.</p> |
