Counter Definitions, Identifier 000h | Hitachi HCS721016CLA382

9.17.3.2.1Counter Definitions

The counter definitions in this section specify the events that a particular counter identifier represents.

9.17.3.2.1.1Identifier 000h

There is no counter associated with identifier 000h. A counter identifier of 000h indicates that there are no additional counters in the log page.

9.17.3.2.1.2Identifier 001h

The counter with identifier 001h returns the number of commands that returned an ending status with the ERR bit set to one in the Status register and the ICRC bit set to one in the Error register.

9.17.3.2.1.3Identifier 002h

The counter with identifier 002h returns the sum of (the number of transmitted Device-to-Host Data FISes to which the host responded with R_ERRP) and (the number of received Host-to- Device Data FISes to which the device responded with R_ERRP).

9.17.3.2.1.4Identifier 005h

The counter with identifier 005h returns the sum of (the number of transmitted Device-to-Host non-Data FISes to which the host responded with R_ERRP) and (the number of received Host-to- Device non-Data FISes to which the device responded with R_ERRP). Retries of non-Data FISes are included in this count.

9.17.3.2.1.5Identifier 009h

The counter with identifier 009h returns the number of times the device transitioned into the PHYRDY state from the PHYNRDY state, including but not limited to asynchronous signal events, power management events, and COMRESET events. If interface power management is enabled, then this counter may be incremented due to interface power management transitions.

9.17.3.2.1.6Identifier 00Ah

The counter with identifier 00Ah returns the number of transmitted Device-to-Host Register FISes with the device reset signature in response to a COMRESET, which were successfully followed by an R_OK from the host.

9.17.3.2.1.7Identifier 00Bh

The counter with identifier 00Bh returns the number of received Host-to-Device FISes of all types (Data and non-Data) to which the device responded with R_ERRP due to CRC error.

9.17.3.2.1.8Identifier 00Dh

The counter with identifier 00Dh returns the number of received Host-to-Device FISes of all types (Data and non-Data) to which the devices responded with R_ERRP for reasons other than CRC error.
