   (notes)
        3-4;    When the data transfer rate of the host becomes very
                high (approximately 8 MB/sec), then the drive must
                output a wait state to pin 27 of the interface to
                extend the transfer cycle. This function is only
                available if the host adapter supports IORDY.
        5-6;    If a host does not support ACMODE then these pins
                should remain OPEN. All requests to spin the motor
                down will be executed.
        7-8;    Remove this jumper to disable the drive's ability to
                automatically spin down when a command has not been
                received from the host after a specific length of time.
        9-10;   In CABLE SELECT (CSEL) mode, the drive can be configured
                as a master or slave drive across the interface cable
                with this jumper shorted. A special cable is required
                to support this function.
