3.1.4 Network interface
The VT6516 directly connect to 16 port RMII PHY or 12 port MII PHY device which compliant with
IEEE standard (Please see IEEE 802.3u Fast Ethernet standard) . Each Fast Ethernet port has following
characteristics:
-
Capable of supporting both 10MBps and 100MBps data rates in half and full duplex modes.
-
Provide a simple management interface (SMI) for port status
-
Perform all functions of the IEEE 802.3 protocol such as frame formatting, frame stripping, collision
handling, deferred, etc.
-
Adjustable preamble ,SFD and inter frame gap (IFG).
-
IEEE 802.3X flow control supported
-
IEEE 802.1D spanning tree protocol support, and all port state of listen and block configurable
3.1.4.1 RMII interface
The VT6516 communicates with the external 10/100M Ethernet transceiver through the reduced MII
(RMII) interface. The signals of RMII interface are described in Table-3-1
