8.2 Field Definitions

Byte 01, Bit 1 – PCR (Parameter Code Reset)

The PCR bit indicates whether you want to set some or all of the

counters, as follows:

0 – Set some of the counters only, as indicated by the PC field.

1 – Reset all of the counters. Current cumulative values will be reset to

0, the Enable Threshold Comparison (ETC) bit will be reset to 0

(see page 8-10), and threshold values will be reset to all FFs. (For

example, the threshold value for a three-byte counter will be reset

to FFFFFFh.)

Note: If you set the PCR bit to 1, be sure that the Parameter List

Length is 0. Otherwise, the CTS will return 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.

Byte 01, Bit 0 – SP (Save Parameters)

The CTS does not support the save parameters function. The valid

value for this bit is 0.

Byte 02, Bits 7 and 6 – PC (Page Control)

If the PCR bit is 0, the PC field specifies what kind of values the CTS

should use to set the counters. If the PCR bit is 1, this bit is ignored.

Valid values for the PC field are as follows:

00b – Set threshold values for the counters listed in the parameter list.

01b – Set current cumulative values for the counters listed in the

parameter list.

10b – Set all threshold values to their default threshold values

(all FFs). Set the ETC bit to 0 (see page 8-10).

11b – Set all current cumulative values to 0.

Note: If you set the PC field to 10b or 11b, be sure that the Parameter

List Length is 0. Otherwise, the CTS will return 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.
