Configuration strap values are latched on power-on reset and system reset. Configuration
straps are identified by an underlined symbol name. Signals that function as configuration
straps must be augmented with an external resistor when connected to a load. Refer to

Technology
This signal is asserted to indicate the receive
medium is non-idle in RMII Mode. When a
10BASE-T packet is received, CRS_DV is
asserted, but RXD[1:0] is held low until the SFD
byte (10101011) is received.
Note:
This signal is asserted to indicate detection of a
collision condition in MII Mode.
Combined with MODE0 and MODE1, this
configuration strap sets the default PHY mode.
See
configuration straps.
Note:
This signal indicates detection of a carrier in MII
Mode.
Link activity LED Indication. This pin is driven
active when a valid link is detected and blinks
when activity is detected.
Note:
This configuration strap is used to disable the
internal 1.2V regulator. When the regulator is
disabled, external 1.2V must be supplied to
VDDCR.
See
configuration straps.
Note:
When REGOFF is pulled high to VDD2A with
an external resistor, the internal regulator is
disabled.
When REGOFF is floating or pulled low, the
internal regulator is enabled (default).

for additional information.
Per the RMII standard, transmitted data
is not looped back onto the receive data
pins in 10BASE-T half-duplex mode.
