Micrel
As far as the PHY is concerned, TXD7-0 are used to convey only packet data. To allow for a direct MAC-to-MAC connection, the
MAC uses TXD7-0 to signal ‘status’ in between frames.
TXD7 – 0 Encoding
Collision Detection
Collisions occur when CRS and TX_EN are simultaneously asserted. For this to work, the PHY must ensure that CRS is not affected
by its transmit path.
