JTAG
Kū ʻo JTAG no Joint Test Action Group a ʻo ia ka inoa maʻamau no ka IEEE standard 1149.1 i kapa ʻia ʻo Standard Test Access Port a me Boundary Scan Architecture.Hoʻohana ʻia kēia maʻamau e hōʻoia i ka hoʻolālā a hoʻāʻo i ka hana o nā papa kaapuni i paʻi ʻia.
Hoʻohana maʻamau ʻia ʻo JTAG i kēia manawa no ka hoʻāʻo ʻana i nā sub-blocks o nā kaapuni hoʻohui i ka wā e hoʻolālā ai i nā papa kaapuni paʻi.Hāʻawi pū ʻo JTAG i kahi hana debugging pono i nā ʻōnaehana i hoʻopili ʻia, e hāʻawi ana i kahi 'puka hope' kūpono i ka ʻōnaehana.I ka hoʻohana ʻana i nā mea hana hoʻopiʻi e like me nā simulators in-circuit e hoʻohana ana iā JTAG ma ke ʻano he hōʻailona hōʻailona, hiki i ka mea papahana ke heluhelu i ka module debug i hoʻohui ʻia i loko o ka CPU ma o JTAG.ʻO ka module debug e hiki ai i ka mea polokalamu ke hoʻopau i ka polokalamu i loko o ka ʻōnaehana hoʻokomo.
SNI interface
ʻO SNI ka pilina ma waena o ka AN a me ka SN.Inā ʻaʻole i like ka helu AN-SNI me ka kiko SNI-SN, hiki ke hana i kahi pilina mamao ma o ke kaila hoʻouna māmā.(Serial Network Interface) He kikowaena pūnaewele serial, i ʻike maʻamau ʻia ma ke ʻano he kikowaena pūnaewele ʻehiku, e like me ka interface MII (Media Independent Interface).
Nā pōmaikaʻi o ka chip Ethernet
Hiki i kēia hoʻonā ke hoʻokūkū maikaʻi ma waena o MAC a me PHY, ʻoiai e hōʻemi ana i ka helu o nā pine a me ka ʻāpana chip.ʻO ka monolithic Ethernet microcontroller kekahi e hōʻemi i ka hoʻohana ʻana i ka mana, ʻoi aku ka nui inā hoʻohana ʻia ke ʻano mana iho.
Kaapuni Ethernet
Hōʻike ʻia ka ʻāpana Ethernet o kahi ʻōnaehana terminal i hoʻokomo ʻia ma lalo nei:
E pili ana i nā huahana
Ke hoʻomau nei ka nui o nā noi e koi ana i ka hoʻopili ʻana iā Ethernet, e hoʻohuli ana i nā mea hoʻohana ʻia ʻo Ethernet i nā wahi ʻoi aku ka paʻakikī.
Ua hoʻolālā ʻia ka DP83848C/I/VYB/YB no ka hoʻokō ʻana i ka paʻakikī o kēia mau noi hou me kahi hana wela lōʻihi e hele aʻe ma mua o ka pae wela ʻoihana maʻamau.ʻO ka DP83848C/I/VYB/YB he mea hilinaʻi nui, hiʻohiʻona, a paʻa i nā kūlana IEEE 802.3 ma luna o nā pae wela he nui mai ka pāʻoihana a i ka wela wela.Ua kūpono kēia hāmeʻa no nā kaiapuni koʻikoʻi e like me nā kahua kikowaena mamao mamao, kaʻa/kaʻa, a me nā noi mana ʻoihana.
Hāʻawi ia i ka pale ESD i hoʻonui ʻia a me ke koho ʻana o kahi interface MII a i ʻole RMII no ka hiki ke maʻalahi i ke koho MPU;i loko o kahi pūʻolo 48 pin.
Hoʻonui ka DP83848VYB i ke kūlana alakaʻi o ka ʻohana PHYTER™ o nā hāmeʻa me kahi ākea wela o ka hana.Kūkulu ʻia ka laina TI o nā transceivers PHYTER ma luna o nā makahiki he ʻumi o ka ʻike Ethernet e hāʻawi i ka hana kiʻekiʻe a me ka maʻalahi e hiki ai i ka mea hoʻohana hope ke hoʻokō maʻalahi e hoʻokō i kēia mau pono noi.
