The MODE[4:0] configuration straps are sampled and latched at power-up/reset and are defined in Section 3.3.1, "Device Mode Select (MODE_SEL[4:0])". PHY Broadcast Mode Configuration Strap ALLPHYAD VIS Configures the default support for PHY Broadcast access using PHY Address 0. The ALLPHYAD configuration strap is sampled and latched at power-up/reset and are defined as fol- lows: 0: Enable PHY Broadcast accesses by default 1: Disable PHY Broadcast accesses by default Refer to Section 3.3.3, "All PHYs Address (ALLPHYAD)" for additional information. LED Mode Configuration Strap LED_MODE VIS Configures the device’s LED behavior as Individual or Tri- Color. All 8 LEDs are configured with identical behavior. The LED_MODE configuration strap is sampled and latched at power-up/reset and is defined as follows: 0: Tri-color-LED mode 1: Individual-LED mode Refer to Section 3.3.4, "LED Mode Select (LED_MODE)" for additional information.
