PROBLEM TO BE SOLVED: To provide the transmitter that relieves a processing load without transfer of fill data in the case of transferring a fixed length packet. SOLUTION: A reception control section 14 receives a fixed length packet from a communication transmission line 14 via a reception control section 13 and an interrupt control section 39 conducts interrupt processing while transferring valid data to a main control section 11 based on valid data length information in the fixed length packet and the valid data are transferred to the main control section 11 via a data status control section 38. Furthermore, while fill data are transferred, the interrupt control section 39 masks interruption and the main control section 11 receives no fill data while the interrupt control section 39 is masked. |
