Santa Cruz Connector Header
A set of three headers (J8, J9, and J11), per the Santa Cruz header specification, are provided for debug purposes and
installing compatible daughter boards. All I/Os on the Santa Cruz header are shared with the PCI signals.
Note: Do not exercise the PCI connector and the Santa Cruz connector header simultaneously.

ARM Debugger
A 20-pin port (J10) is provided ( see Figure 2-7) for installing an ARM Real View debugger that interfaces with the
M1AFS1500-FG484 device.
Note: While using the debugger to run the software, add a jumper from JP16 pin 1 to JP17 pin 1. This will make the
M1AFS1500-FG484 the only part in the chain.
