SMSC DS – LAN91C100FD REV. B
Page 2
Rev. 01-20-06
The LAN91C100FD is based on the LAN91C100 FEAST, functional revision G modified to add full duplex capability. Also
added is a software-controlled option to allow collisions to discard receive packets. Previously, the LAN91C100 supported
a “Diagnostic Full Duplex” mode. Under this mode the transmit packet is looped internally and received by the MAC. This
mode was enabled using the FDUPLX bit in the TCR. In order to avoid confusion, the new, broader full duplex function of
the LAN91C100FD is designated as Switched Full Duplex, and the TCR bit enabling it is designated as SWFDUP. When
the LAN91C100FD is configured for SWFDUP, its transmit and receive paths will operate independently and some
CSMA/CD functions will be disabled. When the controller is not configured for SWFDUP it will follow the CSMA/CD
protocol.
