1.3.1Connectors

J1 is the 10-pin JTAG connector. See Table A-5 on page 26.

J7 and J101 (slot 2 and slot 1) are local (secondary bus) PCI option slots.

J101 (slot 1) can be used for a local processor with the insertion of a PCI Industrial Computer Manufacturers Group (PICMG) Single Board Computer. It is the PCI portion of the PCI-ISA card edge connector. See Section 1.7 and Section 1.9.

J102 (secondary bus) is the optional and connector-less slot. The optional slot is for a third

64-bit PCI connector. The through-holes are provided for installation of a local bus connector. The default build for this board is for two option cards on the local bus. 66MHz operation is limited to two (2) loads on the PCI bus. All connectors are 64-bit.

The J2 and J4 Mictor* (scope pod) connectors provide test points for the all the 64-bit S_AD signals.

The J5 and J6 Mictor connectors are for other PCI control signals, such as C/BE, REQ, and GNT. J6 provides test points for parallel ROM data and address lines.
