Processor System Signals
Table 6 lists the processor system signals by type. All GTL+ signals are synchronous with the
BCLK signal. All TAP signals are synchronous with the TCK signal except TRST#. All CMOS
input signals can be applied asynchronously.

See Section 8.1 for information on the PWRGOOD signal.
These signals are tolerant to 1.5V only. See Table 7 for the recommended pull-up resistor.
These signals are tolerant to 2.5V only. See Table 7 for the recommended pull-up resistor.
These signals are tolerant to 3.3V only.
VCC is the power supply for the core logic.
PLL1 and PLL2 are the power supply for the PLL analog section.
VCCT is the power supply for the system bus buffers.
VREF is the voltage reference for the GTL+ input buffers.
VSS is system ground.
The CMOS, APIC, and TAP inputs can be driven from ground to 1.5V. BCLK, PICCLK, and
PWRGOOD can be driven from ground to 2.5V. The APIC data and TAP outputs are Open-drain
and should be pulled up to 1.5V using resistors with the values shown in Table 7. If Open-drain
drivers are used for input signals, then they should also be pulled up to the appropriate voltage
using resistors with the values shown in Table 7.
