<p>PROBLEM TO BE SOLVED: To reduce the capacity of control data or the like to be written in a ROM area in a one chip microcomputer for equipment control. SOLUTION: Concerning this microcomputer device, a control program P required for control and compressed control data are stored in the ROM area of a microcomputer and an extension program Pr for extending and restoring these compressed and stored control data is stored. In the case of controlling equipment, first of all, the extension program Pr is executed and the control data compressed and stored in the ROM area is extended, restored and written in a RAM area. Afterwards, while referring to these extended and restored control data, the control program P executes prescribed control operation.</p> |
