AUI Signal Pins DO ± AUI Data Out Output When Port 0 is configured for AUI, DO ± are the AUI dif- ferential data out drivers. Data is transmitted with Manchester encoded signaling compliant with IEEE 802.3 standards. DI ± AUI Data In Input When Port 0 is configured for AUI (Control Register Reg 18 bit 2), DI ± are the AUI differential data in receiv- ers. Data is indicated by Manchester encoded signal- ing compliant with IEEE 802.3 standards. PCI/CI+ Pseudo-AUI Collision, AUI Collision Int (-) Input/Input When Interrupt Enable is true (Control Register Reg 18 bit 5) and port 0 is configured for AUI (Control Register Reg 18 bit 2), this pin is configured as PCI. PCI is a sin- gle-ended pseudo-AUI collision in signal. Collision is in- dicated by a 10 MHz pattern. When Interrupt Enable is false (Control Register Reg 18 bit 5) and port 0 is configured for AUI (Control Reg- ister Reg 18 bit 2), this pin is configured as CI+. CI ± are the AUI differential collision in signals. Collision is indi- cated by a 10 MHz pattern compliant with IEEE 802.3 standards. QINT/CI- QuEST Interrupt, AUI Collision Int (-) Output/Input When Interrupt Enable is true (Control Register Reg. 18 bit 5), this pin is configured as QINT. QINT is an ac- tive-low signal which indicates that one of the following conditions has occurred: Link Status Change, Duplex Mode Change, Auto-Negotiation Change, MAU Error. Interrupt status flags and enables for individual condi- tions are reported in the Interrupt Status and Enable Register (Reg 16). When Interrupt Enable is false (Control Register Reg 18 bit 5) and port 0 is configured for AUI (Control Reg- ister Reg 18 bit 2), this pin is configured as CI-. CI ± are the AUI differential collision in signals. Collision is indi- cated by a 10-MHz pattern compliant with IEEE 802.3 standards. QuASI Interface QTX_EN Multiplexed Transmit Enable Input QTX_EN indicates to QuEST that valid transmit data is on QTX_DATA. QTX_EN for all 4 ports is time-division multiplexed onto this signal and is sampled with re- spect to SCLK. The channel’s slot is synchronized to the rising edge of QRST/STRB. QTX_DATA Multiplexed Transmit Data Input QTX_DATA indicates serial NRZ transmit data. QTX_DATA for all 4 ports is time-division multiplexed onto this signal and is sampled with respect to SCLK. The channel’s slot is synchronized to the rising edge of QRST/STRB. QRX_CRS Multiplexed Receive Carrier Sense Output QRX_CRS indicates receive or transmit activity on the network. QRX_CRS for all 4 ports is time-division mul- tiplexed onto this signal and is sampled with respect to SCLK. The channel’s slot is synchronized to the rising edge of QRST/STRB. QRX_VALID Multiplexed Receive Data Valid Output QRX_VALID indicates that valid receive data is on QRX_DATA. QRX_VALID for all 4 ports is time-division multiplexed onto this signal and is sampled with re- spect to SCLK. The channel’s slot is synchronized to the rising edge of QRST/STRB. At the rising edge of re- set, QRX_VALID is sampled to determine PHYAD 3. QRX_DATA Multiplexed Receive Data Output QRX_DATA indicates ser ial NRZ receive data. QRX_DATA for all 4 ports is time-division multiplexed onto this signal and is sampled with respect to SCLK. The channel’s slot is synchronized to the rising edge of QRST/STRB. At the rising edge of reset, QRX_DATA is sampled to determine PHYAD 4. QCLSN Multiplexed Collision Output QCLSN indicates a collision condition on the network. QCLSN for all 4 ports is time-division multiplexed onto this signal and is sampled with respect to SCLK. The channel’s slot is synchronized to the rising edge of QRST/STRB. At the rising edge of reset, QCLSN is sampled to determine PHYAD 2. |
