HSMC User-Defined LEDs
The HSMC port A and B have two LEDs located nearby. There are no board-specific
functions for the HSMC LEDs. However, the LEDs are labeled TX and RX, and are
intended to display data flow to and from the connected HSMC daughtercards. The
LEDs are driven by the Arria II GX device.
