PURPOSE:To automatically set the read frame phase of a buffer memory, to eliminate trouble for operating from the outside each time the configuration of a low-speed signal interface part is changed, and to eliminate the fault cause of signal discontinuity caused by the imperfection of input setting from the outside. CONSTITUTION:An identification information inserting part 23 outputs the identification information of a low-speed signal interface part 20. An identification information detection part 19 of a high-speed signal interface part 10 detects the output of the identification information inserting part 23 and imparts it to a setting part 18 as identification information S3. The setting part 18 imparts an initial set value S4 to a counter 17 based on the identification information S3, and the counter 17 imparts a read frame signal S5 to buffer memories 151-15N and reads contents. |
