15.4.1
Below is a description of the eTSEC interface signals. For RGMII mode details please refer to the
Hewlett-Packard reduced gigabit media-independent interface (RGMII) specification version 1.2a, dated
9/22/2000. RMII mode details follow the RMII Consortium Specification, dated 3/20/1998. All other
modes follow the IEEE 802.3 standard, 2000 Edition. Input signals not used are internally disabled. Except
for TSECn_GTX_CLK, output signals not used are driven low.
