Ethernet MAC Configuration
Taw qhia
SmartFusion Microcontroller Subsystem (MSS) muab ib qho Ethernet MAC nyuaj peripheral.
Tus cwj pwm tiag tiag ntawm Ethernet MAC yuav tsum tau txhais ntawm qib kev thov siv SmartFusion
MSS MAC Driver muab los ntawm Actel.
Hauv daim ntawv no, peb piav qhia yuav ua li cas koj tuaj yeem ua rau MSS MAC piv txwv thiab xaiv seb qhov
Ethernet MAC interface txuas nrog rau MSS I/Os lossis FPGA ntaub.
Yog xav paub ntxiv txog MSS MAC nyuaj peripheral, thov mus saib ntawm Actel SmartFusion
Microcontroller Subsystem Tus neeg siv phau ntawv qhia.
Configuration Options
Enabling/Disabling MAC Instance. Ntawm MSS canvas, koj yuav tsum tau pab (default) lossis lov tes taw MAC piv txwv raws li seb nws puas tau siv rau hauv koj daim ntawv thov tam sim no. Yog tias xiam oob qhab, qhov piv txwv MAC tau tuav hauv qhov pib dua (lub xeev lub zog qis tshaj) tom qab Actel system khau raj code raug tua.
Connectivity Options. Thaum siv A2F200M3F ntaus ntawv, Ethernet MAC, thaum qhib, tsuas tuaj yeem txuas rau MSS I/Os nplooj siab. Thaum siv A2F500M3G ntaus ntawv, koj tuaj yeem xaiv txuas MAC peripheral rau MSS I/Os lossis FPGA ntaub. Nyob rau hauv txhua rooj plaub, MAC kev sib txuas tau txais kev teeb tsa los ntawm Actel system khau raj code. Nco ntsoov tias MSS I/Os faib rau MAC piv txwv yog muaj los txuas rau FPGA ntaub yog MAC piv txwv. Xa mus rau MSS I/O Configuration daim ntawv kom paub meej ntxiv. Txhawm rau siv MAC FPGA cov chaw nres nkoj (yog tias qhov kev xaiv ntawd raug xaiv), koj yuav tsum tau txhawb nqa mus rau qib siab ntawm FABRIC pawg chaw nres nkoj tam sim no ntawm MSS MAC piv txwv. Tom qab ntawd koj tuaj yeem siv FABRIC MAC cov chaw nres nkoj hauv qib tom ntej ntawm hierarchy.
Ethernet MAC Clock xaiv. Yog tias koj qhib MAC peripheral ntawm MSS configurator canvas lub moos MAC raug xaiv (nyeem nkaus xwb) hauv Clock configurator. Siv MSS Clock configurator koj yuav tsum xaiv ib qho ntawm MAC moos hauv qab no.
- Sab nraud 10/100 moos (MAC_CLK tus pin) ntawm SmartFusion ntaus ntawv.
- Lub moos tsim nyob rau hauv MSS Clock Conditioning Circuit (MSS_CCC).

Cov teeb liab no yuav tsum tau lees paub los ntawm PHY thaum ib qho kev txais lossis kev xa tawm nruab nrab tsis nyob twj ywm. PHY ntaus ntawv yuav tsum lees paub MAC_CRSDV thaum cov ntaub ntawv siv tau raug muab rau ntawm RXD teeb liab. |
| MDIO | PADs | Inout | Yog lawm | RMII tswj cov ntaub ntawv nkag thiab tawm. Lub xeev ntawm cov teeb liab tawm tswv yim tuaj yeem tshawb xyuas los ntawm kev nyeem CSR9.19 ntsis. Lub teeb liab tso zis yog tsav los ntawm CSR9.18 ntsis. |
| RXD [1:0] | PADs | In | Yog lawm | Tau txais cov ntaub ntawv rov qab thiab txiav tawm los ntawm PHY. Lub teeb liab RXD[0] yog qhov tseem ceeb me ntsis. |
| TXEN | PADs | Tawm | Yog lawm | Transmit ua. Thaum lees paub, qhia cov ntaub ntawv siv tau rau PHY ntawm TXD chaw nres nkoj. |
| MDC | PADs | Tawm | Yog lawm | RMII tswj moos = 25 MHz. Cov teeb liab no tau tsav los ntawm CSR9.16 ntsis. |
| TXD [1:0] | PADs | Tawm | Yog lawm | Xa cov ntaub ntawv. TXD[0] teeb liab yog qhov tseem ceeb me ntsis. |

Nco tseg:
- PAD cov chaw nres nkoj tau txais kev txhawb nqa mus rau sab saum toj thoob plaws hauv kev tsim hierarchy.
- Cov chaw nres nkoj tsis-PAD yuav tsum tau nce qib ntawm tus kheej mus rau qib siab tshaj plaws los ntawm MSS configurator canvas kom muaj raws li qib tom ntej ntawm hierarchy.
