Ethernet Media Access Controller (MAC)
The MAC subsystem is compliant with the ISO/TEC
802.3 topology for a single shared medium with several
stations. Multiple MII-compliant PHYs are supported.
Features include:
•
•
Serial Interfaces (SPI, I
The Serial Peripheral Interface (SPI) port can be
configured as a master or a slave, supporting the
National
Instruments
The AC'97 port supports multiple codecs for multichannel
audio output with a single stereo input. The I
supports stereo 24-bit audio.
These ports are multiplexed so that the I
over either the AC'97 pins or the SPI pins.
