MVME4100 Single Board Computer Installation and Use (6806800H18D)

3.4.1 Processor COP Header (P4)

There is one standard 16-pin header that provides access to the COP function. The pin

assignments for this header are as follows:

Pin 6 +3.3 V has a 100 W resistor to +3.3 V.

3.4.2 Boundary Scan Header (P5)

The 20-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 are as

follows:
