  • Page 5: Ethernet 10/100 Mbps

    UM2697 Ethernet 10/100 Mbps Ethernet 10/100 Mbps Section 2.3 shows the ethernet 10-100 Mbps communication channel. Figure 4. Ethernet 10/100 Mbps JP15 allows configuring the communication in MII or RMII mode. The current absorption of this section can be estimated by removing SB7 then applying a low impedance current meter or a current probe.

    UM2697 Ethernet 1 Gbps Ethernet 1 Gbps The ethernet 1 Gbps section is depicted here below. Figure 5. Ethernet 1 Gbps The resistors from R85 to R84, from R88 to R91, from R95 to R98 and from R100 to R103 are used to configure the device.

  • Page 7: Emmc And Μsd

    UM2697 eMMC and μSD eMMC and μSD Figure 6 Figure 7 are showing the eMMC and µSD card reader section respectively. From the microcontroller, the signals Data 0÷3, CMD, CLK and FBCLK are shared among these sections and this means only one section can be active at a time. These signals must be connected to the active section by selecting the jumpers from JP17 to JP22 properly: see Figure Figure 6.
