CIRCUIT AND METHOD FOR CONTROLLING BURST TRANSFER

摘要

PROBLEM TO BE SOLVED: To provide a burst transfer control circuit and a burst transfer controlling method which detect an error when burst transfer is made to a memory and can forcedly finish the burst transfer when the error is detected. SOLUTION: When an external function circuit 104 controls data transfer by the burst transfer to a FIFO 103 provided between a transferring side 101 and a part to be transferred 102 according to a transfer control procedure with the transferring side, the circuit 104 detects an error of burst transfer data A in each transfer unit, and immediately outputs the end notice TA of the burst transfer according to the transfer control procedure to the transferring side at the time when the circuit 104 detects the error.
