Protocol
1. Timing
As Command processing can only be carried out one time in a Vertical cycle, it takes the
maximum 1V cycle time for an ACK/Completion to be returned. If the Command
ACK/Completion communication time can be cut shorter than the 1V cycle time, then every
1V cycle can receive a Command.
※
