Bytes 05 and 06 – Parameter Pointer

The Parameter Pointer field indicates the Parameter Code of the first

counter you want to be returned for the requested page. As long as

the value in the Allocation Length field is large enough, the CTS

returns all counters with a Parameter Code greater than or equal to

the code specified in this field. For example, if you specify 0004h for

the Parameter Pointer, the CTS returns information about counters

0004h through 0006h.

The counters are returned in Parameter Code order (unsigned). If the

parameter specified does not exist, the CTS returns the next available

parameter first.

Valid values for this field are 0000h to 0006h. To return all the

counters for either the Write Error Counter page or the Read Error

Counter page, specify 0 for this field and set the Allocation Length to

a sufficient length to receive all bytes (at least 28h).

Notes:

If you set the Page Code field to 00h (Supported Log Pages page),

this field is ignored.

If the value for this field is greater than the Parameter Code for

any of the counters (that is, if you specify a value greater than

0006h), the CTS returns Check Condition status with the sense

key set to Illegal Request (5h), the ASC and ASCQ set to 24h and

00h, and the Fault Symptom Code set to CEh.

Bytes 07 and 08 – Allocation Length

The Allocation Length field specifies the maximum number of bytes

you want the CTS to transfer during the Data In phase. You can

specify any value from 0 to FFFFh for this field. To return all the

counters for either the Write Error Counter page or the Read Error

Counter page, specify at least 28h (40 bytes) for this field.

Note: It is not error to specify a value for the Allocation Length field

that would truncate the information on one of the pages.

Byte 09, Bits 7 and 6 – Vendor Unique

There are no vendor unique definitions for these bits.
