Order Number: 304120 47
Connectors and LEDs—MPCBL0010 SBC
5.2 On-Board Connectors
5.2.1 POST Code Connector (J13)
The 8-bit content of I/O address 80h is serialized into a proprietary protocol and the
output sent to the J13 connector. In manufacturing, a display board is used to
deserialize and display the POST code value on 7-segment LEDs modules.
5.2.2 Extended IPT700 Debug Port Connector (J25)
An Extended ITP700 port connection is included to facilitate debug and BIOS/software
development efforts. This JTAG connection to the processors utilizes voltage signaling
levels that are specific to the Low Voltage Intel
®
Xeon™ Processor family. These levels
must not be exceeded or processor damage may occur. See the Debug Port Design
Guide listed in Appendix A, “Reference Documents” for more information.
