Signal Description
6.13 Processor Internal Pull-Up/Pull-Down
Terminations
§ §
Table 6-16. GND, RSVD, and NCTF Signals
Signal Name Description
Vss Processor ground node
Vss_NCTF Non-Critical To Function: These signals are for package mechanical reliability.
RSVD Reserved: All signals that are RSVD should not be connected on the board.
RSVD_NCTF Reserved Non-critical To Function: RSVD_NCTF should not be connected on the board.
RSVD_TP Test Point: Intel recommends to route each RSVD_TP to an accessible test point. Intel
may required these test point for platform specific debug. Leaving these test point
inaccessible could delay debug by Intel.
