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.
