2.9 Ethernet Management Interface (EMI)
The T1024 processor has two Ethernet Management Interfaces (EMI), EMI1 and EMI2.
EMI2 is only used with 10G Base-T PHY and 2.5G SGMII PHY, which uses 1.2 V pull-
up. EMI1 is used with RGMII PHYs. There are two working modes in the T1024RDB-
PC. The following tables represents the configurations for 10GBase-T and 2.5G SGMII
