<p>PURPOSE:To execute the pattern information content for change without destroying the stored pattern information content, by enabling to change the content of the pattern information already stored at the callout instruction processing through the provision of an information replacing circuit. CONSTITUTION:A callout instruction read from a program input circuit 2 is inputted to an information replacing circuit 8 and a change information detecting circuit 9 inputs a change information read trigger to a change information register 10. The circuit 9 inputs a change information address to a buffer circuit 5 and commands the output of content of the register 10. An operation circuit 6 inputs a readout command trigger to the buffer circuit 5 with an operation preparatory command inputted from an instruction interpreting circuit 3, fetches the output of the buffer circuit 5 in which the pattern information is already changed by as mentioned above for specified operation.</p> |
