To comply with Davicom recommendations on connecting this device, J27-4 and J27-5 (RJ45 connector, CT) should be connected to the VCCA side of L2. In the current schematics (ETHERNET, Sheet 3/4), the VCCA side of L2 is connected to MN10-1 and MN10-2 (DM9161A, AVDDR). For additional information, refer to the Davicom datasheet for DM9161A and associated Application Notes available on http://www.davicom.com.tw/. 6.2 TWI line pullups for Fast Mode operation In order to use the TWI in Fast Mode (up to 400 Kbits/s), the default 10 KΩ resistors R38 and R39 should be replaced by smaller values (e.g., 2.2 KΩ). Note that there is no need to change the pull-up resistors if the TWI is used in Standard Mode (up to 100 Kbits/s).
