ABSTRACT:
A method is provided for checking the integrity of a full duplex multi-word serial transfer between first and second devices, the transfer including an actual last word. The method includes transmitting a count word from the first device to the second device, the count word indicating a number of words to be transmitted including an expected last word, transmitting the actual last word from the first device to the second device, and transmitting, substantially simultaneously to transmission of the actual last word, a check code word from the second device to the first device, the check code word having a selected value if the actual last word is the expected last word, and another value otherwise. The method also includes determining a transfer error if the value of the check code word is other than the selected value. A system is also provided for performing the method.
