$VG 0$KV, Margin Control Subpage 01h | Maxtor 10K III instruction

SCSI Description

/CTIKPThe Margin%QPVTQNControl5WDRCIGsubpage (see Table 5-98)contains parameters that set and report margin control values for usage between the initiator/target pair on subsequent synchronous and paced transfers.

A MODE SELECT command will return the current settings for the initiator/target pair. Fields that are not implemented will be reported as zero.

The Driver Strength field indicates the relative amount of driver source currently used by the driver. The Driver Strength field affects both the strong and week drivers. A larger value indicates more driver source current.

The Driver Precompensation field indicates the relative difference between the weak driver and the strong driver amplitudes when precompensation is enabled. A larger value indicates a larger difference between the weak and strong amplitudes.

The Driver Asymmetry field indicates the relative difference between the amplitudes of asserted and negated signals launched from the driver. A larger value indicates a relatively stronger asserted signal compared to the negated signal.

The Driver Slew Rate field indicates the relative difference between the assertion and negation magnitudes divided by the rise or fall time. A larger value indicates a faster slew rate.
