10.21.3.2 Counter Identifiers
Each counter begins with a 16-bit identifier. Table 67 defines the counter value for each identifier. Any unused
counter slots in the log page should have a counter identifier value of 0h.
Optional counters that are not implemented shall not be returned in log page 11h. A value of '0' returned for a counter
means that there have been no instances of that particular event. There is no required ordering for event counters
within the log page; the order is arbitrary and selected by the device vendor.
For all counter descriptions, 'transmitted' refers to items sent by the device to the host and 'received' refers to items
received by the device from the host.
Bits 14:12 of the counter identifier convey the number of significant bits that counter uses. All
counter values consume a multiple of 16-bits. The valid values for bits 14:12 and the
corresponding counter sizes are:
1h 16-bit counter
2h 32-bit counter
3h 48-bit counter
4h 64-bit counter
Any counter that has an identifier with bit 15 set to one is vendor specific. This creates a vendor specific range of
counter identifiers from 8000h to FFFFh. Vendor specific counters shall observe the number of significant bits 14:12
as defined above.
