This board has eight dual color (Green/Red) surface mount LEDs are provided for general purpose
use.
- A logic 0 is driven on the I/O port to turn the LED ON.
- A logic 1 is driven on the I/O port to turn the LED OFF.
lists the assignment for each users LED and describes board reference description
signaling standard and schematic name for the USER LEDs located on the HSMC. These are all
2.5V LVCMOS signals. Each channel has a bi-colored LED. The 4 states of each bi-color LED (Off,
green, red, orange) can be used to identify received or transmitted rate or any other state that the
user would like. The LEDs are driven from user logic located inside the host device on the host
board.
