V

CTERM

System bus termination voltage.

GND

System ground.

N/C

No connection can be made to these pins.

TERMA, TERMB

The Itanium 2 processor uses two pins to control the on-die termination 
function, TERMA and TERMB. Both of these termination pins must be 
pulled to VCTERM in order to terminate the system bus using the on-die 
termination resistors. Both of these termination pins must be pulled to 
GND in order to use off-die termination.

TUNER1, TUNER2

TUNER1 is used to control the slew rate of the system bus I/O buffers. 
The nominal value for the TUNER1 resistor is 150 ohms. A lower 
resistance will cause a faster slew rate. TUNER2 is used to control the 
termination resistance for the system bus I/O buffers. The nominal value 
for the TUNER2 resistor is 150 ohms. A lower resistance will cause a 
lower on-die termination resistance. On-die termination mode will only 
be selected if the TERMA and TERMB pins are terminated as indicated 
above. 

VCCMON, VSSMON

These pins provide a remote sense connection from the processor to the 
power pod. No connections that constitute a current load can be made to 
these pins.
