Abstract

PURPOSE:To ensure a highly efficient transfer of information, by varying the scan time to a circuit adaptor in accodance with the presence of absence of transfer of information as well as the type of the information tranferred between the circuit adaptor and the circuit control common part. CONSTITUTION:Both the transfer-enable-or-unable-information plus a transfer request to be given to a circuit adaptor 1 is informed to a circuit control common part 3, and a prescribed number of information are transferred 4 en bloc with just one scan to the adaptor 1 for control 8. At the same time, the end of transfer of information is informed to the part 3. The part 3 gives an indication 2 of information transfer control to the adaptor 1 during scan of the adaptor 1 and in accordance with the presence or absence of the transfer-enable-or-unable information plus the transfer request and others. And the selection of the adaptor 1 is kept for the scan during transfer of information.
