How to configure the ADSP-SC584 ethernet to 1000mbps speed


I am using ADSP-SC584 EzKit v1.4 BOM 2.4 board. I want to configure the EMAC0 ethernet to 1000mbps speed. I have verified with the 100mbps speed and tried to modify the EMAC0_MAC_CFG and PADS0_CFG registers to achieve 1000mbps but the connection is not established.

Could you please help me with the configuration need to be done both hardware level and software level.
