Intel® Xeon® Processor E5-1600 v2/E5-2600 v2 Product Families 

Datasheet Volume One of Two

SVIDALERT_N

Serial VID alert.

SVIDCLK

Serial VID clock. 

SVIDDATA

Serial VID data out.

BIST_ENABLE

BIST Enable Strap. Input which allows the platform to enable or 

disable built-in self test (BIST) on the processor. This signal is 

pulled up on the die, refer to 

 for details. 

BMCINIT

BMC Initialization Strap. Indicates whether Service Processor Boot 

Mode should be used. Used in combination with FRMAGENT and 

SOCKET_ID inputs.

• 0: Service Processor Boot Mode Disabled. Example boot 

modes: Local PCH (this processor hosts a legacy PCH with 

firmware behind it), Intel QPI Link Boot (for processors one 

hop away from the FW agent), or Intel QPI Link Init (for 

processors more than one hop away from the firmware agent). 

• 1: Service Processor Boot Mode Enabled. In this mode of 

operation, the processor performs the absolute minimum 

internal configuration and then waits for the Service Processor 

to complete its initialization. The socket boots after receiving a 

“GO” handshake signal via a firmware scratchpad register.

This signal is pulled down on the die, refer to 

 for details.

CAT_ERR_N

Indicates that the system has experienced a fatal or catastrophic 

error and cannot continue to operate. The processor will assert 

CAT_ERR_N for nonrecoverable machine check errors and other 

internal unrecoverable errors. It is expected that every processor 

in the system will wire-OR CAT_ERR_N for all processors. Since 

this is an I/O land, external agents are allowed to assert this land 

which will cause the processor to take a machine check exception. 

This signal is sampled after PWRGOOD assertion.

On the processor, CAT_ERR_N is used for signaling the following 

types of errors:

• Legacy MCERR’s, CAT_ERR_N is asserted for 16 BCLKs.
• Legacy IERR’s, CAT_ERR_N remains asserted until warm or 

cold reset.

CPU_ONLY_RESET

Reserved, not used.

ERROR_N[2:0]

Error status signals for integrated I/O (IIO) unit:

• 0 = Hardware correctable error (no operating system or 

firmware action necessary)

• 1 = Non-fatal error (operating system or firmware action 

required to contain and recover)

• 2 = Fatal error (system reset likely required to recover)

FRMAGENT

Bootable Firmware Agent Strap. This input configuration strap 

used in combination with SOCKET_ID to determine whether the 

socket is a legacy socket, bootable firmware agent is present, and 

DMI links are used in PCIe* mode (instead of DMI2 mode).
The firmware flash ROM is located behind the local PCH attached to 

the processor via the DMI2 interface.This signal is pulled down on 

the die, refer to 

 for details.
