Hi TI,
These are the pin functionality description of TX_CTRL and RX_CTRL mentioned in the datasheet....Kindly explain the functionality w.r.t both RGMII and GMII.
1)TX_CTRL pin denotes TX_EN on rising edge of GTX_CLK and denotes a logic derivative of TX_EN and TX_ER on the falling edge of GTX_CLK.
TX_ER = GMII_TX_ER (XOR) GMII_TX_EN
GMII_TX_ER and GMII_TX_EN are logical equivalent signals in GMII standard.
2)RX_CTRL denotes RX_DV on rising edge of RX_CLK and denotes a logic derivative of RX_DV and RX_ER on the falling edge of RX_CLK
RX_ER = GMII_RX_ER (XOR) GMII_RX_DV
MII_RX_ER, and GMII_RX_DV are logical equivalent signals in GMII standard.
Thanks & Regards
