A.6.4 Receive Output Enable
The receive output enable pin, RX_EN, forces the receive and collision
MII outputs into the high-impedance state. More specifically, when
RX_EN is deasserted, the RX_CLK, RXD[3:0], RX_DV, RX_ER, and
COL pins are placed in a high-impedance state.
RX_EN can be used to “wire OR” the outputs of many L80227 devices
in multiport applications where only one device may be receiving at a
time, such as in a repeater application. Monitoring the CRS pin from
each individual port enables the repeater to assert RX_EN only to that
L80227 device that is receiving data. The method reduces, by eight per
device, the number of pins and PCB traces a repeater core IC requires.
