7.2.3. UTP Mode and SNI Interface
SNI interface to MAC (only operates in 10Base-T when the SNI interface is enabled)
Table 24. UTP Mode and SNI Interface
DUPLEX
(Pin 38)
L
The duplex pin is pulled low to support the 10Base-T half duplex function.
10Base-T half duplex is the specified default mode in the SNI interface.
H
The RTL8201CP also supports full duplex in SNI mode. The duplex pin is
pulled high to support 10Base-T full duplex function.

7.2.4. Fiber Mode and MII Interface
The RTL8201CP only supports 100Base-FX when Fiber mode is enabled. ANE (Auto-Negotiation
Enable) and SPEED configuration is ignored when Fiber mode is enabled.

7.3. Flow Control Support
The RTL8201CP supports flow control indications. The MAC can program the MII register to indicate to
the PHY that flow control is supported. When the MAC supports the Flow Control mechanism, setting
bit 10 of the ANAR register using the MDC/MDIO SMI interface, then the RTL8201CP will add the
ability to its NWay ability. If the Link partner also supports Flow Control, then the RTL8201CP can
recognize the Link partner’s NWay ability by examining bit 10 of ANLPAR (register 5).
