Depending on the base board, the USB interface can be realized either as host1 or
device0, the signals have the following meaning:
At the module specific pins of the system connector a second host interface (host0) is
provided with the differential data lines DP0 and DN0.
Ethernet interface The ConnectCore 9M 2443 module has a 10/100Mbit Ethernet controller with
integrated MAC and PHY on board.
Features:
 Embedded 16Kbyte FIFO for packet buffers
 Support burst-mode read for highest performance applications
 Configurable Interrupt pin with programmable hold-off timer
 Compatible with IEEE802.3, 802.3u standards
 Integrate Fast Ethernet MAC/PHY transceiver in one chip
 10Mbps and 100Mbps data rate
 Full and half duplex operations
 10/100Mbps Auto-negotiation operation
 Twisted pair crossover detection and auto-correction (HP Auto-MDIX)
 IEEE 802.3x flow control for full-duplex operation
 Back-pressure flow control for half-duplex operation
 Wake-on-LAN capabilities:
• Detection of a change in the network link state
• Receipt of a Magic Packet
 LED pins for various network activity indications
The Ethernet controller is connected to CS5#. Its programmable polarity interrupt
output is connected to the interrupt input EINT9 of the CPU.
Global signals on the system connector only indicate the Link/Activity-LED is being
used.
On the base board a transformer with 1:1 turns ratio on TX and 1:1 on RX should be
used. For instance, PULSE H11022.
