<p><P>PROBLEM TO BE SOLVED: To automate the operation mode changing process executed conventionally by software, without requiring confirmation of a condition for the change when the operation mode of a microcomputer is changed. <P>SOLUTION: The operation mode changing device has a mode register 106 for setting the motion mode of the microcomputer, a plurality of condition flags 101, 102 and 103 indicating conditions for allowing the operation mode change, a load signal producing part 104 for producing a load signal 105 based on the theoretical product of the plurality of condition flags, and a pre-mode register 107 for storing the data loaded to the mode register 106 based on the load signal 105. The data setting in the pre-mode register 107 is executed based on the command of the microcomputer. <P>COPYRIGHT: (C)2004,JPO</p> |
