Tool/software:
Regarding the Isolate Mode, when enabled, what happens to the states of the RMII interface? In IEEE 802.3-2015 22.2.4.1.6 Isolate, MII and GMII specifies transmit signals are ignored and receive signals are non-driving high impedance.
Does the subject part number's RMII interface behave in this manner as well? That is, when ISOLATE is enabled, the PHY will not respond to TX_EN and TX_D[1:0] signals as well as presents non-driving high impedance on RX_ER, CRS_DV and RX_D[1:0].
