Table 2–28 lists the general user-defined LED component reference and
manufacturing information.
HSMC User-Defined LEDs
The HSMC Port A and Port B have two LEDs located nearby. There are no
board-specific functions for the HSMC LEDs; however, the HSMC LEDs are labeled
TX and RX, and are intended to display data flow to and from connected HSMC
daughter cards. The LEDs are driven by the Cyclone III device.
Table 2–29 lists the HSMC user-defined LED board reference number, schematic
signal name, and corresponding Cyclone III device pin number.
Table 2–30 lists the HSMC user-defined LED component reference and manufacturing
information.
