PURPOSE:To select properly one of plural processing programs in accordance with the purpose by incorporating preliminarily them in a microcomputer unit or the like. CONSTITUTION:At an initial start time, a control part 10 designates an initialization detecting part 11 to read states of terminal pins P0-P2 in a condition selecting part of an input port 1 and transmits these states to a processing selecting part 12. The processing selecting part 12 selects, for example, a program 21 of a processing B in accordance with initialization states of terminal pins P0- P2. Hereafter, this program 21 is operated to execute the processing B by a microcomputer unit 1. Initialization states of terminal pins P0-P2 in the condition selecting part are changed to execute another processing. |
