Electrical Specifications

7.4 System Agent (SA) Vcc VID

The V

CCSA

is configured by the processor output pins VCCSA_VID[1:0].

VCCSA_VID[0] output default logic state is low for 2nd Generation Intel

Core

family

mobile processors.

Note: During boot, the processor V

CCSA

voltage is 0.9 V. The V

CCSA

may change only once

during the reset sequence.

Note: For Ultra products, for power optimization purposes, the VCCSA_VID may change

dynamically during the processor’s operation.

Table 7-2 specifies the different VCCSA_VID configurations.

7.5 Reserved or Unused Signals

The following are the general types of reserved (RSVD) signals and connection

guidelines:

• RSVD – these signals should not be connected.

• RSVD_TP – these signals should be routed to a test point.

• RSVD_NCTF – these signals are non-critical to function and may be left un-

connected.

Arbitrary connection of these signals to V

CCSA,

, V

, or

to any other signal (including each other) may result in component malfunction or

incompatibility with future processors. See Chapter 8 for a pin listing of the processor

and the location of all reserved signals.

For reliable operation, always connect unused inputs or bi-directional signals to an

appropriate signal level. Unused active high inputs should be connected through a

resistor to ground (V

). Unused outputs maybe left unconnected; however, this may

interfere with some Test Access Port (TAP) functions, complicate debug probing, and

prevent boundary scan testing. A resistor must be used when tying bi-directional

signals to power or ground. When tying any signal to power or ground, a resistor will

also allow for system testability.
