Notes:
1. Refer to Chapter 6 and Chapter 8 for signal description details.
2. SA and SB refer to DDR3 Channel A and DDR3 Channel B.
3. The maximum rise/fall time for UNCOREPWRGOOD is 20 ns.
All Control Sideband Asynchronous signals are required to be asserted/de-asserted for
at least
10 BCLKs with a maximum Trise/Tfall of 6 ns for the processor to recognize
the proper signal state. See Section 7.10 for the DC specifications.
7.8 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. Some small portion of the I/O pins may support only one of these
standards.
