Table 2–27 lists the user-defined LED schematic signal names and their corresponding
Arria II GX pin numbers.
Table 2–28 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. The LEDs are labeled TX and RX, and displays data
flow to and from the connected HSMC daughtercards. The LEDs are driven by the
Arria II GX device.
Table 2–29 lists the HSMC user-defined LED schematic signal names and their
corresponding Arria II GX pin numbers.
