speed
Gigabit, Indicates the valid data is
GMII 100Mbps, present on the data bus of
Mode 10Mbps TXD. Synchronous to the
rising edge of GTX_CLK
(Gigabit) or TXC_CLK
(10/100M).
Gigabit, The TX_CTL indicates a
RGMII 100Mbps, signal like TX_EN at the
Mode 10Mbps rising edge of TXC. A signal
like TX_ER is derived by the
logical operation of latched
“TX_EN” and the value at the
falling edge of TXC.
