Abstract
A information processing apparatus capable of avoiding deadlock between transmission and reception operations of data. A transmission section transmits a data block including a predetermined amount of data and a sequence number. A reception section receives the data block. A packet inspection controller of the reception section determines whether the received data block is correct or wrong, based on a result of detection of an error in the data and a result of comparison between an expected value of the sequence number and a value of the sequence number included in the data block. The expected value of the sequence number is changed to a next value when it is determined that the data block is wrong a predetermined number of times.
