Ib kauj ruam thiab sijhawm
Qee cov ntawv sau npe yuav tsum tau nyeem lossis sau ntawv nyob rau hauv ib lub voj voog uas tau muab los tom qab ua kom muaj lub teeb liab tswj. Txij li thaum lub moos I / O thiab cov khoom siv txuas ntxiv khiav ntawm qhov nrawm hauv hom nres, ib kauj ruam dhau los ntawm cov cai no yuav tsis ua raws li lub sijhawm. Nyob nruab nrab ntawm ob kauj ruam ib zaug, I / O moos yuav tau khiav ntau lab lub voj voog. Txhawm rau ua tiav kev nyeem lossis sau cov ntawv sau npe nrog lub sijhawm yuav tsum tau ua, tag nrho nyeem lossis sau cov kab ke yuav tsum tau ua raws li kev ua haujlwm atomic khiav lub cuab yeej ntawm qhov nrawm. Qhov no tuaj yeem ua tiav los ntawm kev siv macro lossis kev hu xov tooj los ua kom tiav cov lej, lossis siv cov haujlwm khiav-rau-tus cursor hauv ib puag ncig debugging
Nkag mus rau 16-ntsis sau npe
Lub Atmel AVR peripherals feem ntau muaj ntau lub npe 16-ntsis uas tuaj yeem nkag tau los ntawm 8-ntsis cov ntaub ntawv tsheb npav (xws li: TCNTn ntawm 16-ntsis timer). Daim ntawv teev npe 16-ntsis yuav tsum tau siv byte siv ob txoj haujlwm nyeem lossis sau ntawv. Kev tawg nyob rau hauv nruab nrab ntawm 16-ntsis nkag los yog ib kauj ruam dhau los ntawm qhov xwm txheej no yuav ua rau muaj txiaj ntsig yuam kev.
Txwv tsis pub I/O tso npe nkag
Qee cov ntawv sau npe tsis tuaj yeem nyeem yam tsis muaj kev cuam tshuam rau lawv cov ntsiab lus. Cov ntawv sau npe no suav nrog cov uas muaj cov chij uas raug tshem tawm los ntawm kev nyeem ntawv, lossis cov ntaub ntawv sau npe tsis txaus (piv txwv li: UDR).

Thaum programming ntawm JTAG interface, TCK zaus yog txwv los ntawm qhov siab tshaj plaws zaus ntsuas ntawm lub hom phiaj ntaus ntawv, thiab tsis yog lub moos zaus siv.
Thaum siv RC oscillator sab hauv, nco ntsoov tias qhov zaus yuav txawv ntawm lub cuab yeej mus rau lub cuab yeej thiab cuam tshuam los ntawm qhov kub thiab txias.CC kev hloov. Yuav tsum ceev faj thaum qhia txog lub hom phiaj moos zaus.
JTAGEN thiab OCDEN fuses
Tus J.TAG interface yog enabled siv JTAGEN fuse, uas yog programmed los ntawm lub neej ntawd. Qhov no tso cai rau nkag mus rau JTAG programming interface. Los ntawm cov txheej txheem no, OCDEN fuse tuaj yeem ua haujlwm tau (los ntawm lub neej ntawd OCDEN tsis yog programmed). Qhov no tso cai rau kev nkag mus rau OCD txhawm rau txhawm rau txhim kho kev debugging lub cuab yeej. Lub software pem hauv ntej-kawg yuav ib txwm ua kom ntseeg tau tias OCDEN fuse raug tso tseg tsis muaj programmed thaum xaus kev sib tham, yog li txwv tsis pub siv hluav taws xob tsis tsim nyog los ntawm OCD module. Yog tias JTAGEN fuse tsis txhob txwm ua tsis taus, nws tsuas tuaj yeem rov qhib tau siv SPI lossis High Voltage programming txoj kev.
Yog tias JTAGEN fuse yog programmed, JTAG interface tseem tuaj yeem cuam tshuam rau hauv firmware los ntawm kev teeb tsa JTD me ntsis. Qhov no yuav ua rau code un-debuggable, thiab yuav tsum tsis txhob ua thaum sim kev sib tham debug. Yog tias cov cai no twb tau ua tiav ntawm Atmel AVR ntaus ntawv thaum pib kev sib tham debug, Atmel-ICE yuav lees paub RESET kab thaum txuas. Yog tias cov kab no raug xaim raug, nws yuav yuam kom lub hom phiaj AVR ntaus ntawv rov pib dua, yog li tso cai rau JTAG kev sib txuas.
Yog tias JTAG interface yog enabled, JTAG pins tsis tuaj yeem siv rau lwm txoj haujlwm pins. Lawv yuav nyob twj ywm rau JTAG pins mus txog rau JTAG interface yog xiam oob qhab los ntawm kev teeb tsa JTD me ntsis los ntawm qhov program code, lossis los ntawm kev tshem tawm JTAGEN fuse los ntawm programming interface.
Tswv yim:
Nco ntsoov xyuas lub "siv sab nraud rov pib dua" checkbox nyob rau hauv ob qho tib si programming dialog thiab debug xaiv dialog thiaj li tso cai rau lub Atmel-ICE los lees paub RESET kab thiab rov qhib JTAG interface ntawm cov khoom siv uas khiav cov cai uas cuam tshuam rau JTAG interface los ntawm kev teeb tsa JTD ntsis.
Cov xwm txheej IDR/OCDR

Thaum daim ntawv thov kev pab cuam hauv hom khiav sau ib byte ntawm cov ntaub ntawv mus rau OCDR sau npe ntawm AVR ntaus ntawv tau debugged, Atmel-ICE nyeem cov nqi no tawm thiab qhia nws hauv cov lus qhov rais ntawm software pem hauv ntej-kawg. Cov ntawv sau npe OCDR raug tshuaj xyuas txhua 50ms, yog li kev sau ntawv rau nws ntawm qhov zaus siab dua yuav tsis ua rau cov txiaj ntsig ntseeg tau. Thaum AVR ntaus ntawv poob lub zog thaum nws tab tom kho, cov xwm txheej OCDR spurious yuav raug tshaj tawm. Qhov no tshwm sim vim tias Atmel-ICE tseem tuaj yeem xaiv lub cuab yeej raws li lub hom phiaj voltage poob hauv qab AVR qhov tsawg kawg nkaus kev khiav hauj lwm voltage.
