Byte 02, Bit 4 – Enable Threshold Comparison (ETC)

The ETC field indicates whether threshold comparisons for the

counter are enabled or disabled, as follows:

0 – Threshold comparisons for this counter are disabled.

1 – Threshold comparisons are performed on this counter.

If threshold comparisons are enabled, the CTS compares the

cumulative value to the threshold value when the cumulative value is

updated. When the conditions specified by the Threshold Met Criteria

(TMC) bit are met (see below), the CTS returns Check Condition

status with the sense key set to Unit Attention (6h), the ASC and

ASCQ set to 5Bh and 01h, and the Fault Symptom Code set to CAh.

Byte 02, Bits 3 and 2 – Threshold Met Criteria (TMC)

The TMC field specifies the conditions under which the CTS will

generate a Unit Attention (6h) sense key when comparing the current

cumulative value to the threshold value. Threshold comparisons are

made when the cumulative value is updated. Valid values for this

field are as follows:

00b – Return Unit Attention when the cumulative value is updated

01b – Return Unit Attention when the updated cumulative value

equals the threshold value

10b – Return Unit Attention when the updated cumulative value is

not equal to the threshold value

11b – Return Unit Attention when the updated cumulative value is

greater than the threshold value

Byte 02, Bit 1 – Reserved

This bit is reserved.

Byte 02, Bit 0 – List Parameter (LP)

List parameters are not supported by the CTS, so this bit must be 0.
