• Select (Address) — This LED is on whenever the brain board is addressed (read from or written to) on the Pamux bus. It is off
• Watchdog — This LED stays on if the Pamux bus is idle (no strobe is present) for more than 1.2 seconds. It is off otherwise. Note

otherwise. For each operation the LED stays on for about 250 msec, so if the bus is very active the LED may appear constantly on.
that unlike the Select LED, this LED monitors overall bus activity.
