Table 52 Phy Event Counter Identifiers - Hitachi CinemaStar P7K500 Specifications

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.

Counter Definitions
The counter definitions in this section specify the events that a particular counter identifier
represents.
8.20.3.2.1.1 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.
8.20.3.2.1.2 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.
8.20.3.2.1.3 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,
