Counter Definitions
The counter definitions in this section specify the events that a particular counter identifier represents.
Identifier 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.
Identifier 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.
Identifier 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).
Identifier 003h
The counter with identifier 003h returns the number of transmitted Device-to-Host Data FISes to which the host
responded with R_ERRP.
Identifier 004h
The counter with identifier 004h returns the number of received Host-to-Device Data FISes to which the device
responded with R_ERRP. The count returned for identifier 004h is not required to be equal to the sum of the
counters with identifiers 00Fh and 010h.
Identifier 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.
Identifier 006h
The counter with identifier 006h returns the number of transmitted Device-to-Host non-Data FISes to which the host
responded with R_ERRP. Retries of non-Data FISes are included in this count.
Identifier 007h
The counter with identifier 007h returns 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.
Identifier 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.
