在设置 DP83826 以用于 EtherCAT® 时，以下寄存器的写入值如下：

LED 0
Write to PHY register 0x19 value 0x8020 (Auto-MDIX enable and enable LED0 config) 
Write to PHY register 0x18 value 0x0080 (Active High polarity)
LED 1 
Write to PHY register 0x460 value 0x0005 (100Mbit speed)
Write to PHY register 0x469 value 0x0004 (Active High polarity)
Write to PHY register 0x304 value 0x0008 (Set pin 31 function to LED1) Auto negotiate enable configuration
