General User Input/Output

Table 2–26 lists the user-defined LED schematic signal names and their corresponding

Arria II GX pin numbers.

Table 2–27 lists the user-defined LED component reference and the manufacturing

information.

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.

Table 2–28 lists the HSMC user-defined LED schematic signal names and their

corresponding Arria II GX pin numbers.
