7.6 Test Access Port (TAP) Connection
Due to the voltage levels supported by other components in the Test Access Port
(TAP) logic, Intel recommends the processor be first in the TAP chain, followed by any
other components within the system. A translation buffer should be used to connect to
the rest of the chain unless one of the other components is capable of accepting an
input of the appropriate voltage. Two copies of each signal may be required with each
driving a different voltage level.
The processor supports Boundary Scan (JTAG) IEEE 1149.1-2001 and IEEE
1149.6-2003 standards. A few of the I/O pins may support only one of those
standards.

DC Specifications
The processor DC specifications in this section are defined at the processor pins,
unless noted otherwise. See Signal Description on page 77 for the processor pin
listings and signal definitions.
• The DC specifications for the DDR3/DDR3L signals are listed in the Voltage and
Current Specifications section.
• The Voltage and Current Specifications section lists the DC specifications for the
processor and are valid only while meeting specifications for junction temperature,
clock frequency, and input voltages. Read all notes associated with each
parameter.
• AC tolerances for all DC rails include dynamic load currents at switching
frequencies up to 1 MHz.
