    The following sections describe the various board features, including jumpers, LEDs, test points, system connections, and switches. A top view of the EVB9303M is shown in Figure 2.1. Note: The LAN9303M device is RoHS compliant. However, support components on the EVB9303M board are not necessarily RoHS compliant. Power Switch +5V Power...
  • Page 4 LED1 circuit as a pull-up, and the LED2 circuit as a pull-down. To illuminate LED1, the LAN9303M will drive the cathode of the LED1 low. To illuminated LED2, the LAN9303M will drive the anode of the LED2 high.
  • Page 5 All strap values are read during power-up and on the rising edge of the nRST signal. Once the strap value is set, the LAN9303M will drive the LEDs high or low for illumination according the strap value. For other designs which may use these pins as GPIOs or interrupts, refer to the LAN9303M datasheet for additional information.
