- Kitendaji cha mlinzi (WDG_FS23)
Chati ya uanzishaji ya FS23 example
- Kielelezo cha 1 kinatoa mfano wa zamaniample ya uanzishaji wa programu ya FS23. Baada ya kuweka upya kwa MCU kutolewa (hali ya RSTB iko juu), MCU inaweza kuanza uanzishaji wa FS23. Uanzishaji lazima ufanywe ndani ya dirisha maalum la 256 ms INIT.
- Kuendesha ABIST ni hiari, ingawa inapendekezwa kwa programu za ASIL B. ABIST inaweza kuendeshwa mara nyingi mfululizo. Katika hii exampna, MCU hukagua sababu ya uwekaji upya wa MCU (POR, LPOFF, kushindwa salama) na kuchukua hatua ipasavyo. Kisha MCU huandika rejista za usalama za INIT, na kumalizia na ukaguzi wa upunguzaji wa mzunguko wa INIT (CRC).
- Hatua inayofuata ni usanidi wa walinzi, na kufungua ukaguzi wa mzunguko wa INIT CRC, ikifuatiwa na viboreshaji vya walinzi ili kufuta kihesabu hitilafu. Onyesho la kwanza la kuonyesha upya shirika hufunga awamu ya INIT.
- Kwa hivyo, viburudisho vya walinzi vifuatavyo lazima vitumwe kulingana na usanidi wa wakati wa walinzi. Pindi kihesabu cha hitilafu kinapoondolewa, pini za usalama FS0B na LIMP0 zinaweza kutolewa.

Utaratibu wa kukokotoa FS0B na au LIMP0
Wakati matokeo ya kutofaulu ya FS0B yanapothibitishwa kuwa ya chini na kifaa kwa sababu ya hitilafu, au baada ya kuwasha, baadhi ya masharti lazima yathibitishwe kabla ya kuruhusu pini ya FS0B kutolewa na kifaa.
Masharti haya ni:
- Hakuna hitilafu inayoathiri FS0B iliyoripotiwa
- Kaunta ya hitilafu yenye hitilafu sawa na sifuri
- Kifaa katika Hali ya Kawaida
- Kifaa hakiko katika hali ya Utatuzi na si katika modi ya INIT
- Rejesta ya FS_FS0B_LIMP0_REL iliyojazwa thamani sahihi, kulingana na thamani ya sasa ya WD_TOKEN[15:0] kulingana na Jedwali la 6. Rejelea Jedwali 56 kutoka kwa Karatasi ya data ya FS23:

Utaratibu wa majibu ya mlinzi
- [1] Rejelea Sehemu ya 20.2 kutoka laha ya data ya FS23.
- Mlinzi hutumia funguo mbili, 0x5AB2 (thamani chaguo-msingi baada ya POR) na 0xD564 ili kuthibitisha jibu. Ufunguo huhifadhiwa kwenye rejista ya WD_TOKEN, na hubadilishwa badala ya kila uboreshaji mzuri wa WD.
- MCU husoma rejista ya WD_TOKEN na kuandika jibu sahihi (thamani ya rejista ya WD_TOKEN) kupitia SPI/I2C katika rejista ya WD_ANSWER, kwa muda ufaao. Kaunta ya hitilafu ya WD inaongezwa wakati jibu si sahihi au halijatolewa kwa wakati ufaao, au halijatolewa kabisa mwishoni mwa kipindi cha walinzi. Rejelea
- Jedwali 35 kutoka kwa karatasi ya data ya FS23.
- Urekebishaji mzuri wa kwanza wa walinzi hufunga awamu ya INIT. Usahihishaji huu mzuri wa kwanza wa shirika la uangalizi hutumwa na MCU chini ya ms 256 (muda wa kipindi chaguomsingi). Kisha dirisha la walinzi linaendeshwa na MCU lazima ionyeshe walinzi kila kipindi.

Utaratibu wa kukokotoa SPI/I2C CRC
CRC ya biti 8 inahitajika kwa kila amri ya kuandika na kusoma ya SPI. Ukokotoaji wa CRC unatokana na hisabati ya mgawanyiko wa polynomial, modulo mbili.
Vigezo vya CRC ni:
- Polynomial: x^8+x^4+x^3+x^2+1 (identified by 0x1D)
- Mbegu: 0xFF.
Kwa mawasiliano ya SPI
Ujenzi wa ujumbe wa SPI unajumuisha anwani ya rejista, sehemu ya kusoma/kuandika, data na CRC. Rejelea Jedwali 65 na 66 kutoka laha ya data ya FS23. B32 lazima iwekwe kwa 1 kutekeleza amri ya kuandika, na kwa 0 kutekeleza amri ya kusoma.

Unapotumia mawasiliano ya SPI, ingizo la hesabu ya CRC ni neno la biti 24 linaloundwa na anwani ya rejista, sehemu ya kusoma/kuandika na data.
Kwa mawasiliano ya I2C
Ujenzi wa ujumbe wa I²C unajumuisha anwani ya kifaa, sehemu ya kusoma/kuandika, anwani ya usajili, data na CRC. Rejelea Jedwali 61 kutoka kwa karatasi ya data ya FS23. B32 lazima iwekwe 0 kutekeleza amri ya kuandika, na kwa 1 kutekeleza amri ya kusoma.

Utaratibu wa kuhesabu INIT CRC
Rejesta zisizo salama za INIT zinalindwa na CRC. Polynomia sawa na mbegu zinazotumiwa kwa SPI/I²C CRC zinahitajika ili kukokotoa INIT CRC hii: Polynomia ni x^8+x^4+x^3+x^2+1 (iliyotambuliwa na 0x1D) ikiwa na thamani ya mbegu ya 0xFF.
Hatua tatu zinahitajika ili kukokotoa INIT CRC:
- Soma rejista za usanidi wa FS na utoe vipande vifuatavyo.
- Unda neno la biti 58 kwa kuunganisha biti 58.
- Kokotoa INIT CRC kidogo kwa kutumia 0x1D polynomial. Takwimu hapa chini inatoa example kwa bitwise CRC computation algorithm.
