Processor Configuration Registers
2.10.5 RID—Revision Identification Register
This register contains the revision number of the processor root port. These bits are
read only and writes to this register have no effect.
8RW1C 0b Uncore
Master Data Parity Error (PMDPE)
This bit is set by a Requester (Primary Side for Type 1
Configuration Space header Function) if the Parity Error Response
bit in the Command register is 1b and either of the following two
conditions occurs:
• Requester receives a Completion marked poisoned
• Requester poisons a write Request
If the Parity Error Response bit is 0b, this bit is never set.
Reset Value of this bit is 0b.
This bit will be set only for completions of requests encountering
ECC error in DRAM.
Poisoned peer-2-peer posted forwarded will not set this bit. They
are reported at the receiving port.
7RO 0bUncore
Fast Back-to-Back (FB2B)
Not Applicable or Implemented. Hardwired to 0.
6RO 0h Reserved (RSVD)
5RO 0bUncore
66/60MHz capability (CAP66)
Not Applicable or Implemented. Hardwired to 0.
4RO 1bUncore
Capabilities List (CAPL)
Indicates that a capabilities list is present. Hardwired to 1.
3RO-V 0b Uncore
INTx Status (INTAS)
This bit indicates that an interrupt message is pending internally
to the device. Only PME and Hot-plug sources feed into this
status bit (not PCI INTA–INTD assert and deassert messages).
The INTA Assertion Disable bit, PCICMD1[10], has no effect on
this bit.
INTA emulation interrupts received across the link are not
reflected in this bit.
Note: PCI Express* Hot-Plug is not supported on the processor.

Revision Identification Number (RID)
This is an 8-bit value that indicates the revision identification
number for the root port. Refer to the Mobile 3rd Generation
