CRS  
VO8  
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.  
(RMII Mode)  
Note:  
Per the RMII standard, transmitted data  
is not looped back onto the receive data  
pins in 10BASE-T half-duplex mode.

Note 2.1 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  
Section 3.7, "Configuration Straps," on page 37 for additional information.
