JTAG Chain and Board

The MVME2500 is designed to work with separate JTAG board rather than with an on-
board JTAG multiplexer. The chip can support up to a 6-scan port and the board's boundary
scan requires the following to function: ASSET hardware, JTAG board, and JTAG cable.
The MVME2500 provides a 60-pin header that can connect to the JTAG board using a
custom cable.
The JTAG board provides three different connectors for the ASSET hardware, flash
programming and the MVME2500 JTAG connector. The board is equipped with TTL buffers
to help improve the signal quality as it traverses over the wires.
