... Enhanced Ethernet Transceiver The MC68160B Enhanced Ethernet Interface Circuit is a BiCMOS device which supports both IEEE 802.3* Access Unit Interface (AUI) and 10BASE–T Twisted Pair (TP) Interface media connections through external isolation transformers. It encodes NRZ data to Manchester data and supplies the signals which are required for data communication via 10BASE– ...

... LOOP as a test mode is enabled that disrupts normal operation. Twisted Pair Automatic Polarity Correction Enable: When TPAPCE is high, automatic polarity correction is enabled, and MC68160B will internally correct for a polarity fault on the receive circuit. Additionally, when TPAPCE is high, the presence of a polarity fault is indicated on TPPLR ...

... Twisted Pair Receiver Inputs (TPRX+, TPRX–) are reversed, TPPLR will be driven to the low logic state to indicate the fault. TPPLR remains low when the MC68160B has automatically corrected for the reversed wires. If the twisted pair link integrity tests fail, this output will be driven to the high logic state ...

... CS0 CS1 CS2 NOTE: In standby mode, the MC68160B consumes less power supply current than in any other mode. Additionally, in the standby mode, all of the controller inputs and outputs are driven to the high impedance state. When the standby mode is deasserted, an internal reset pulse of approximately 6.0 s duration is generated. ...

... Collision is the occurrence of simultaneous transmit activity by two or more stations on the network. In the event of collision, the data transfer paths are unaffected. If the MC68160B is in the twisted pair mode, collision is detect by simultaneous receive and transmit activity the AUI mode, collision is detected by activity on the ACX+/– pins. In either case, if collision is detected, the CLSN pin will assert to notify the communications controller ...
