PURPOSE:To make easy the repair, by enabling to move the storage data of RAM to a data collector and the data of the data collector to RAM. CONSTITUTION:An RAM14 is provided with a data collector read/write memory 14a, count memory 14b, error flag memory 14c, read flag memory 14d and stack memory 14e. The data is stored, when the data is read out from an ECR1 to a data collector 5 in the data collector read/write memory 14a when the data is written in from the data collector 5 to the ECR1. In a count memory b, data is stored while the number of transfer byte is counted up when the data is moved from the ECR1 to the data collector 5 and storage is made while the transfer byte number is counted down when the data is moved from the data collector 5 to the ECR1. |
