PROBLEM TO BE SOLVED: To provide a semiconductor device capable of improving data transfer efficiency.SOLUTION: A semiconductor device includes: a serial interface 17 that transmits and receives data; a descrambler 32 that receives data scrambled using an LFSR value via the serial interface 17, and descrambles it using the LFSR value; an LFSR value detection unit 36 that detects the LFSR value used for the scrambling of the data, from an SKP OS that is transmitted from a data-transmission-side component 21A in a predetermined time interval; an LFSR value comparison unit 38 that compares the LFSR value detected by the LFSR detection unit 36 with the LFSR value used by the descrambler 32; and a controller 40 that makes the data-transmission-side component 21A execute recovery on the basis of a result of the LFSR value comparison unit 38. |
