12.4
The EPHY is an IEEE 802.3 compliant 10/100 Ethernet physical transceiver. The EPHY can be configured
to support 10BASE-T or 100BASE-TX applications. The EPHY is configurable via internal registers
which are accessible through the MII management interface as well as limited configurability using the
EPHY register map.
There are five basic modes of operation for the EPHY:
Freescale Semiconductor
•
•
1 = Far end fault detect is disabled
0 = Far end fault detect on receive and transmit is enabled. This applies only while auto-negotiation
1 = Disable MII loopback
0 = MII transmit data is looped back to the MII receive pins
1 = Enable jabber detection
0 = Disable jabber detection
1 = Disable 10BASE-T link integrity test
0 = 10BASE-T link integrity test enabled
1 = 10BASE-T receive polarity correction is disabled
0 = 10BASE-T receive polarity is automatically corrected
1 = Un-aligned mode. Available only in symbol mode
0 = Aligned mode
1 = Symbol mode and bypass 4B/5B encoder and decoder
0 = Normal mode
1 = Bypass the scrambler and de-scrambler
0 = Normal
1 = High-impedance twisted pair transmitter. Analog loopback mode overrides and forces this bit
0 = Normal operation
1 = Transmit and receive data regardless of link status
0 = Normal operation
Power down/initialization
Auto-negotiate
