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. However, the LEDs are labeled TX and RX, and are
intended to display data flow to and from the connected HSMC cards. The LEDs are
driven by the Stratix IV GX device.
Table 2–29 lists the HSMC user-defined LED schematic signal names and their
corresponding Stratix IV GX pin numbers.
Table 2–30 lists the HSMC user-defined LED component reference and the
manufacturing information.
