Abstract
PURPOSE:To facilitate a folding test by providing a folding test instruction register, a command generating part and a selector to secure a folding function for the test data. CONSTITUTION:When a folding test instruction is received by a program mode part 7 from a central controller, a folding test command is sent to a folding test instruction register 17 and both receiving and transmitting commands are sent to a register group 19 from a command generating part 18. A selector 20 changes the connection routes to secure connection between a buffer T port 11 and a buffer R port 15. Then the transfer is started for folding test data received via a common bus interface 5. The folding test data stored in the port 11 via a DMA mode part 10 is transferred to the port 15. Furthermore the folding test data is sent to the central controller via the part 10 and the interface 5.
