Table 4.19 PC (page control)

Value

Description

 

 

00b

Current threshold values

01b

Current cumulative values

10b

Default threshold values

11b

Default cumulative values

The "PC" bits are ignored by the drive. The drive assumes that current cumulative parameters are selected.

The "Parameter List Length" field specifies the length in bytes of the parameter list that is located in the Data-Out Buffer. If a parameter list length results in the truncation of any log parameter, the HDD terminates this command with CHECK CONDITION status (ILLEGAL REQUEST [=5] / Invalid field in CDB [=24-00]).

A "Parameter List Length" of zero indicates that no pages shall be transferred. This condition shall not be considered an error.

The HDD does not support that the application client should send pages in ascending order by page code value if the Data-Out Buffer contains multiple pages.
