Claim:
1. A method for transferring data between a memory and a destination memory of a motor control device of a vehicle the method comprising: performing, by a DMA controller, a DMA transaction comprising a sequence of one or more DMA write transfers to write data to the destination memory of the motor control device of the vehicle, assigning a respective timestamp to a final DMA write transfer of the sequence of DMA write transfers and storing the timestamp at the destination memory for the DMA transaction; and proving that the destination memory of the motor control device has been refreshed to detect that the destination memory comprises current data associated with a current DMA transaction rather than a previous data associated with a previous DMA transaction, based on verifying that the timestamp associated with the current data is different from a timestamp associated with the previous data; using the data in the destination memory for controlling an actuator only if the destination memory is detected to comprise current data.
