Three LEDs per port are provided by Samurai-6M/6MX (ADM6996M/MX): Link/Act, Duplex/Col and Speed. The
dual-color LED mode is also supported by Samurai-6M/6MX (ADM6996M/MX). For easy production purpose, the
test signal is sent to each LED at power on reset stage. The LED display mode is controlled by:
1.
2. LED_MODE: It is the value latched on the EDI pin during the power on reset. It’s also used to control the dual

Status
These pins have no power on reset values on them, and Samurai-6M/6MX (ADM6996M)
uses active low value to drive the LED. So the output values of these pins after the power
on reset are shown as follows:
1. First period: This period lasts 1.28 s for LED on test. Samurai-6M/6MX
2. Second period: This period lasts 0.48 s for LED off test. Samurai-6M/6MX
3. Normal Period: This period indicates the link status.
