then this counter may be incremented due to interface power management transitions.
8.20.3.2.1.4 Identifier 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.
8.20.3.2.1.5 Identifier 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_ERR
8.20.3.2.1.6 Identifier 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_ERR
error.

READ LOG EXT Log Page 11h
READ LOG EXT log page 11h is one page (512 bytes) in length. The first Dword of the log page contains
information that applies to the rest of the log page. Software should continue to process counters until a
counter identifier with value 0h is found or the entire page has been read. A counter identifier with value 0h
indicates that the log page contains no more counter values past that point. Log page 11h is defined in 0.

Counter n Identifier
Phy event counter identifier that corresponds to Counter n Value. Specifies the particular event
counter that is being reported. The Identifier is 16 bits in length.
Valid identifiers are listed in 0.
Counter n Value
Value of the Phy event counter that corresponds to Counter n Identifier. The number of significant bits
is determined by Counter n Identifier bits 14:12 (as defined in section 4.3.2). The length of Counter n
Value shall always be a multiple of 16-bits. All counters are one-extended. For example, if a counter
is only physically implemented as 8-bits when it reaches the maximum value of 0xFF, it shall be
one-extended to 0xFFFF. The counter shall stop (and not wrap to zero) after reaching its maximum
value.
