ITHEYIBHILE YOMYALELO

Imiyalelo yetafile ibonelela ngendlela yokudlulisa idatha phakathi kwesithuba sememori yenkqubo yeFlash kunye nesithuba sememori yedatha yezixhobo ze-dsPIC33/PIC24. Eli candelo libonelela ngesishwankathelo semiyalelo yetheyibhile esetyenziswe ngexesha lodweliso lwenkqubo yememori yenkqubo yoFlash. Kukho imiyalelo emine yetheyibhile esisiseko:

• TBLRDL: Itheyibhile ifundeka Phantsi
• TBLRDH: Itheyibhile eFundiweyo Phezulu
• TBLWTL: Itheyibhile Bhala Phantsi
• TBLWTH: Itheyibhile Bhala phezulu

Umyalelo we-TBLRDL usetyenziselwa ukufunda ukusuka kumasuntswana[15:0] wendawo yememori yenkqubo. Umyalelo we-TBLWTL usetyenziselwa ukubhala kumasuntswana[15:0] wesithuba sememori yenkqubo yeFlash. I-TBLRDL kunye ne-TBLWTL zinokufikelela kwimemori yenkqubo yeFlash kwimowudi yeLizwi okanye kwimo yeByte.

I-TBLRDH kunye ne-TBLWTH imiyalelo isetyenziselwa ukufunda okanye ukubhala kwiibits[23:16] zesithuba sememori yeprogram. I-TBLRDH kunye ne-TBLWTH inokufikelela kwimemori yenkqubo yeFlash kwi-Word okanye i-Byte mode. Kuba imemori yenkqubo yeFlash inamabhithi angama-24 kuphela ububanzi, imiyalelo ye-TBLRDH kunye ne-TBLWTH inokujongana ne-byte ephezulu yememori yenkqubo yeFlash engekhoyo. Le byte ibizwa ngokuba yi "phantom byte". Nakuphi na ukufunda kwephantom byte kuya kubuya 0x00. Ukubhalela kwi-phantom byte akunasiphumo. Imemori yenkqubo ye-24 bit-bit inokuthathwa njengezithuba ezimbini zecala necala le-16-bit, kunye nesithuba ngasinye sabelana ngoluhlu lwedilesi efanayo. Ke ngoko, imiyalelo ye-TBLRDL kunye ne-TBLWTL ifikelela kwindawo "ephantsi" yememori yenkqubo (PM[15:0]). Imiyalelo ye-TBLRDH kunye ne-TBLWTH ifikelela kwindawo "ephezulu" yememori yenkqubo (PM[31:16]). Nakuphi na ukufunda okanye ukubhala kwi-PM[31:24] kuya kufikelela kwi-phantom (engasetyenziswanga) byte. Xa nayiphi imiyalelo yetheyibhile isetyenziswa kwimo ye-Byte, i-Byte encinci eBalulekileyo (LSb) yedilesi yetafile iya kusetyenziswa njenge-byte ekhethiweyo yokukhetha. I-LSb imisela ukuba yeyiphi i-byte kwindawo ephezulu okanye ephantsi yememori yenkqubo efikelelweyo.

Umzobo 2-1 ubonisa indlela imemori yenkqubo yeFlash ebhekiswa ngayo kusetyenziswa imiyalelo yetafile. Idilesi yememori yenkqubo ye-24-bit yenziwe kusetyenziswa amasuntswana [7:0] yerejista ye-TBLPAG kunye nedilesi esebenzayo (EA) ukusuka kwirejista ye-W echazwe kumyalelo wetafile. I-24-bit Program Counter (PC) iboniswe kuMzobo 2-1 ukuze kubhengezwe. Amasuntswana angama-23 aphezulu e-EA asetyenziselwa ukukhetha indawo yememori yenkqubo yeFlash.

Kwimiyalelo yetafile yemowudi ye-Byte, i-LSb yerejista ye-EA isetyenziselwa ukukhetha ukuba yeyiphi i-byte ye-16-bit yegama lememori yenkqubo yeFlash ejongiwe; '1' ikhetha amasuntswana[15:8] kwaye '0' ikhethe amasuntswana[7:0]. I-LSb yerejista ye-EA ayihoywa kumyalelo wetafile kwimo yeLizwi. Ukongeza kwidilesi yememori yenkqubo yeFlash, umyalelo wetafile ukwachaza irejista yeW (okanye iW Register Pointer kwindawo yenkumbulo), engumthombo wedatha yememori yenkqubo yeFlash eza kubhalwa, okanye indawo yokufikela yenkqubo yeFlash. inkumbulo ifundwe. Kumsebenzi wokubhala itheyibhile kwimo ye-Byte, amasuntswana[15:8] yomthombo Irejista esebenzayo ayihoywa.

Ukusebenzisa Imiyalelo yokuFunda kwiTheyibhile
Ukufundwa kwetheyibhile kufuna amanyathelo amabini:

1. Isalathisi seeDilesi sisekwa kusetyenziswa irejista ye-TBLPAG kunye nenye yeerejista ze-W.
2. Imixholo yememori yenkqubo yeFlash kwindawo yedilesi inokufundwa.

 

1. FUNDA IMODE YEGAMA
   Ikhowudi eboniswe kwiEksample 2-1 kunye EksampLe 2-2 ibonisa indlela yokufunda igama lememori yenkqubo yeFlash usebenzisa imiyalelo yetafile kwimo yeLizwi.
2. FUNDA IMODE YEBYTE
   Ikhowudi eboniswe kwiEksample 2-3 ibonisa umqhubi we-post-increment kwi-read of the low byte, ebangela ukuba idilesi kwirejista yokuSebenza inyuke ngenye. Oku kucwangcisa i EA[0] kwi '1' yokufikelela kwibyte ephakathi kumyalelo wesithathu wokubhala. I-post-yandiso yokugqibela iseti i-W0 ibuyele kwidilesi elinganayo, ikhomba indawo yememori yenkqubo yeFlash elandelayo.
3. ITHEYIBHILE BHALA IIMALI
   Imiyalelo yokubhala kwitheyibhile ayibhali ngokuthe ngqo kwimemori yeprogram engaguqukiyo. Endaweni yoko, itafile bhala imiyalelo bhala iiletshi ezigcina idatha yokubhala. Iirejista zeedilesi ze-NVM kufuneka zifakwe kwidilesi yokuqala apho kufuneka kubhalwe khona idatha. Xa zonke iiletshi zokubhala zilayishiwe, owona msebenzi wokulungisa inkumbulo uqalwa ngokwenza ulandelelwano olukhethekileyo lwemiyalelo. Ngexesha lenkqubo, i-hardware idlulisela idatha kwiilatshi zokubhala kwimemori yeFlash. Iiletshi zokubhala zihlala ziqala kwidilesi 0xFA0000, kwaye zanda nge-0xFA0002 yokucwangcisa amagama, okanye nge-0xFA00FE yezixhobo ezinenkqubo yokukrola.

Phawula: Inani leeletshi zokubhala liyahluka ngokwesixhobo. Jonga kwisahluko esithi "Inkumbulo yeNkqubo yeFlash" kwiphepha ledatha yesixhobo esithile ngenani leeletshi zokubhala ezikhoyo.

IINCWADI ZOKULAWULWA

Iirejista ezininzi zoMsebenzi oKhethekileyo (SFRs) zisetyenziselwa ukucwangcisa imemori yenkqubo yeFlash ukucima nokubhala imisebenzi: NVMCON, NVMKEY, kunye neerejista zeedilesi zeNVM, NVMADR kunye neNVMADU.

Irejista yeNVMCON
Irejista ye-NVMCON yirejista yolawulo oluphambili lweFlash kunye nenkqubo/yokucima imisebenzi. Le rejista ikhetha ukuba ukucima okanye umsebenzi weprogram uya kwenziwa kwaye unokuqalisa inkqubo okanye ukucima umjikelo. Irejista ye-NVMCON iboniswe kwiRejista ye-3-1. Ibhayithi esezantsi ye-NVMCON iqwalasela uhlobo lomsebenzi we-NVM oza kwenziwa.

NVMKEY Bhalisa
Irejista ye-NVMKEY (jonga iRejista 3-4) yirejista ebhaliweyo kuphela esetyenziselwa ukuthintela ukubhala ngengozi kwe-NVMCON enokonakalisa imemori yeFlash. Nje ukuba ivulwe, ibhalela kwi-NVMCON ivunyelwe kumjikelo womyalelo omnye apho bit WR inokusetwa ukubhengeza ukucima okanye inkqubo yesiqhelo. Ukunikezelwa kweemfuno zexesha, ukuvala uphazamiseko kuyafuneka.
Yenza la manyathelo alandelayo ukuqalisa ukucima okanye ulandelelwano lwenkqubo:

1. Khubaza ukuphazamisa.
2. Bhala i-0x55 kwi-NVMKEY.
3. Bhala i-0xAA ku-NVMKEY.
4. Qala umjikelo wokubhala inkqubo ngokucwangcisa i-WR bit (NVMCON[15]).
5. Yenza imiyalelo emibini ye-NOP.
6. Buyisela iziphazamiso.

UKUKHUBAZA IZIPHAMAMA
Ukuvala iziphazamisi kuyafuneka kuyo yonke imisebenzi yeFlash ukuqinisekisa iziphumo eziyimpumelelo. Ukuba uphazamiseko lwenzeka ngexesha lolandelelwano lokuvula lwe-NVMKEY, lunokuthintela ukubhala kwi-WR bit. Ulandelelwano lokuvula lwe-NVMKEY kufuneka lwenziwe ngaphandle kokuphazamiseka, njengoko kuxoxwe ngayo kwiCandelo 3.2 "irejista ye-NVMKEY".

Ukuphazamiseka kunokukhubazwa kwenye yeendlela ezimbini, ngokukhubaza i-Global Interrupt Enable (GIE bit), okanye ngokusebenzisa umyalelo we-DISI. Umyalelo we-DISI awukhuthazwa kuba ukhubaza kuphela ukuphazamiseka kwe-Priority 6 okanye ngaphantsi; ngoko ke, indlela yeGlobal Interrupt Enable kufuneka isetyenziswe.

I-CPU ibhalela kwi-GIE ithathe imijikelo yemiyalelo emibini phambi kokuba ichaphazele ukuhamba kwekhowudi. Imiyalelo emibini ye-NOP iyafuneka emva koko, okanye inokutshintshwa ngayo nayiphi na eminye imiyalelo yomsebenzi oluncedo, njengokulayisha i-NVMKEY; oku kusebenza kuzo zombini iinkqubo ezimiselweyo nezicacileyo. Ukunyamekela kufuneka kuthatyathwe xa kuphinda kunikwe amandla ukuphazamisa ukwenzela ukuba i-NVM yesiqhelo ejoliswe kuyo ingavumeli ukuphazamisa xa umsebenzi obizwayo wangaphambili ubakhubaze ngenxa yezinye izizathu. Ukujongana noku kwiNdibano, i-stack push kunye ne-pop ingasetyenziselwa ukugcina ubume be-bit ye-GIE. Kwi-C, ukuguquguquka kwe-RAM kungasetyenziselwa ukugcina i-INTCON2 ngaphambi kokucoca i-GIE. Sebenzisa olu landelelwano lulandelayo ukuvala iziphazamisi:

1. Tyhila i-INTCON2 kwisitaki.
2. Coca intwana yeGIE.
3. Ii-NOP ezimbini okanye ubhalele kwi-NVMKEY.
4. Qala umjikelo weprogram ngokucwangcisa i-WR bit (NVMCON[15]).
5. Buyisela imo yeGIE ngePOP yeINTCON2.

Iirejista zeedilesi ze-NVM
Iirejista ezimbini zeDilesi ye-NVM, i-NVMADU kunye ne-NVMADR, xa zidibene, zenza i-24-bit EA yomqolo okhethiweyo okanye igama lemisebenzi yokucwangcisa. Irejista ye-NVMADU isetyenziselwa ukubamba iibhithi ezisibhozo eziphezulu ze-EA, kwaye irejista ye-NVMADR isetyenziselwa ukubamba i-bits ye-16 ephantsi ye-EA. Ezinye izixhobo zinokubhekisa kwezi rejista njenge-NVMADRL kunye ne-NVMADRH. Iirejista zeDilesi ye-NVM kufuneka zisoloko zikhomba kumda wamagama omyalelo ophindwe kabini xa usenza umsebenzi wokwenza inkqubo yegama lomyalelo ophindwe kabini, umda womqolo xa usenza umsebenzi wodweliso lwenkqubo okanye umda wephepha xa usenza umsebenzi wokucima iphepha.

UKUQHUBEKA IXESHA UKUZENZA INKQUBO (RTSP)

I-RTSP ivumela usetyenziso lomsebenzisi ukuguqula imixholo yememori yenkqubo yeFlash. I-RTSP iphunyezwa kusetyenziswa i-TBLRD (iTheyibhile eFundiweyo) kunye ne-TBLWT (iTheyibhile yokuBhala) imiyalelo, irejista ye-TBLPAG, kunye neerejista zoLawulo lwe-NVM. Nge-RTSP, usetyenziso lomsebenzisi lunokucima iphepha elinye lememori yeFlash kunye neprogram nokuba ngamagama amabini omyalelo okanye ukuya kuthi ga kwi-128 amagama omyalelo kwizixhobo ezithile.

Ukusebenza kwe-RTSP
Uluhlu lwememori yenkqubo ye-dsPIC33/PIC24 Flash ilungelelaniswe kumaphepha okucima anokuqulatha ukuya kuthi ga kwimiyalelo eyi-1024. Ukhetho lwenkqubo yamagama amabini luyafumaneka kuzo zonke izixhobo kwiintsapho ze-dsPIC33/PIC24. Ukongeza, izixhobo ezithile zinekhono lokucwangcisa, elivumela ukucwangciswa kwamagama omyalelo angama-128 ngexesha. Ukucwangcisa kunye nokucima imisebenzi ihlala isenzeka kwigama eliphindwe kabini lenkqubo, umqolo okanye imida yephepha. Jonga kwisahluko "Inkumbulo yeNkqubo yeFlash" kwiphepha ledatha yesixhobo esithile malunga nokufumaneka kunye neesayizi zoluhlu lwenkqubo, kunye nobukhulu bephepha lokucima. Imemori yenkqubo yeFlash isebenzisa ukubamba izithinteli, ezibizwa ngokuba ziiletshi zokubhala, ezinokuqulatha ukuya kuthi ga kwimiyalelo ye-128 yedatha yokucwangcisa ngokuxhomekeke kwisixhobo. Ngaphambi komsebenzi wokwenyani weprogram, idatha yokubhala kufuneka ilayishwe kwiilatshi zokubhala. Ulandelelwano olusisiseko lwe-RTSP kukuseta iSikhombisi seTheyibhile, irejista ye-TBLPAG, kwaye emva koko wenze uluhlu lwemiyalelo ye-TBLWT ukulayisha iiletshi zokubhala. Ukucwangcisa kwenziwa ngokumisela iibhithi zolawulo kwirejista yeNVMCON. Inani lemiyalelo ye-TBLWTL kunye ne-TBLWTH efunekayo ukulayisha iiletshi zokubhala lilingana nenani lamagama eprogram aza kubhalwa.

Phawula: Kucetyiswa ukuba irejista ye-TBLPAG igcinwe phambi kokuba ilungiswe ize ibuyiselwe emva kokusetyenziswa.

ISILUMKO
Kwezinye izixhobo, amasuntswana oLungiselelo agcinwe kwiphepha lokugqibela lenkqubo yomsebenzisi wesithuba senkumbulo yeFlash kwicandelo elibizwa ngokuba, “I-Flash Configuration Bytes”. Ngezi zixhobo, ukwenza umsebenzi wokucima iphepha kwiphepha lokugqibela lememori yenkqubo kucima i-bytes yoLungiso lweFlash, eyenza ukhuseleko lwekhowudi. Ke ngoko, abasebenzisi akufuneki benze imisebenzi yokucima iphepha kwiphepha lokugqibela lememori yenkqubo. Oku akuyiyo inkxalabo xa iibits zoqwalaselo zigcinwa kwisithuba senkumbulo yoqwalaselo kwicandelo elibizwa ngokuba, "Iirejista zoLungiselelo lweSixhobo". Jonga kwiMephu yeMemori yeNkqubo kwisahluko "seMemori yeMemori" kwiphepha ledatha ethile yesixhobo ukubona ukuba zibekwe phi na iibits zoLungiso.

Imisebenzi yeFlash Programming
Inkqubo okanye umsebenzi wokucima uyimfuneko kucwangciso okanye ukucima imemori yenkqubo yeFlash yangaphakathi kwimo ye-RTSP. Inkqubo okanye umsebenzi wokucima umiselwa ixesha ngokuzenzekelayo sisixhobo (jonga kwiphepha ledatha ethile yesixhobo ngolwazi lwexesha). Ukucwangcisa i-WR bit (NVMCON[15]) iqalisa umsebenzi. I-WR bit iyacinywa ngokuzenzekelayo xa umsebenzi ugqityiwe. I-CPU iyama de umsebenzi wocwangciso ugqitywe. I-CPU ayizukwenza nayiphi na imiyalelo okanye iphendule kuphazamiseko ngeli xesha. Ukuba kukho nakuphi na ukuphazamiseka okwenzekayo ngexesha lomjikelo weprogram, baya kuhlala belindile de ugqibezele umjikelo. Ezinye izixhobo ze-dsPIC33/PIC24 zinokubonelela ngememori yenkqubo yeFlash encedisayo (jonga kwisahluko esithi “Memory Organisation” secwecwe ledatha yesixhobo esithile ngeenkcukacha), esivumela ukuphunyezwa komyalelo ngaphandle kwe-CPU Stalls ngelixa imemori yenkqubo yeFlash iyacinywa kunye/okanye icwangciswe. Ngakolunye uhlangothi, imemori yenkqubo yeFlash encedisayo inokucwangciswa ngaphandle kwe-CPU Stalls, ukuba nje ikhowudi iphunyeziwe kwimemori yenkqubo yeFlash yomsebenzisi. Ukuphazamiseka kwe-NVM kungasetyenziswa ukubonisa ukuba umsebenzi wodweliso wenkqubo ugqityiwe.

Phawula

1. Ukuba isiganeko se-POR okanye se-BOR senzeka ngelixa ukucinywa kwe-RTSP okanye ukusebenza kwenkqubo kuqhubeka, umsebenzi we-RTSP uyanqanyulwa ngoko nangoko. Umsebenzisi kufuneka aqhube umsebenzi we-RTSP kwakhona emva kokuba isixhobo siphumile kuSetha ngokutsha.
2. Ukuba i-EXTR, SWR, WDTO, TRAPR, CM okanye IOPUWR Ukuseta kwakhona isiganeko kwenzeka ngelixa ukucinywa kwe-RTSP okanye ukusebenza kweprogram kuqhubeka, ifowuni iya kuphinda isetyenziswe kuphela emva kokuba umsebenzi we-RTSP ugqityiwe.
