Headers

This section describes the pin assignments of the Headers on the MVME3100. For Header
settings, refer to
5.3.1

Boundary Scan Header (J24)

The 14-pin boundary scan header provides an interface for programming the on-board
PLDs and for boundary scan testing/debug purposes. The pin assignments for this header
