UKUZIHLELA NGESIKHATHI ESIQHUBEKAYO (RTSP)

I-RTSP ivumela uhlelo lokusebenza lomsebenzisi ukuthi luguqule okuqukethwe kwememori yohlelo lwe-Flash. I-RTSP yenziwa kusetshenziswa imiyalelo ye-TBLRD (Ithebula Elifundwayo) kanye ne-TBLWT (Ithebula Lokubhala), irejista ye-TBLPAG, namarejista okulawula i-NVM. Nge-RTSP, uhlelo lokusebenza lomsebenzisi lungasula ikhasi elilodwa lememori ye-Flash futhi luhlele amagama amabili eziyalo noma amagama eziyalo angafika kwangu-128 kumadivayisi athile.

Ukusebenza kwe-RTSP
I-dsPIC33/PIC24 Flash program memory array ihlelwe ngamakhasi okusula angaqukatha imiyalelo efika ku-1024. Inketho yokuhlela yamagama amabili iyatholakala kuwo wonke amadivayisi emindenini ye-dsPIC33/PIC24. Ngaphezu kwalokho, amadivayisi athile anekhono lokuhlela imigqa, okuvumela ukuhlela amagama emiyalelo afika ku-128 ngesikhathi. Imisebenzi yokuhlela nokusula ihlala yenzeka kumagama emisebenzi yokuhlela aphindwe kabili, imigqa noma ikhasi. Bheka isahluko esithi “Flash Program Memory” seshidi ledatha ledivayisi ethile ukuze uthole ukutholakala nosayizi bomugqa wokuhlela, kanye nosayizi wekhasi we-erasing. Imemori yohlelo lwe-Flash isebenzisa ama-buffers okugcina, abizwa ngokuthi ama-write latches, angaqukatha imiyalelo efinyelela ku-128 yedatha yokuhlela kuye ngedivayisi. Ngaphambi kokusebenza kwangempela kokuhlela, idatha yokubhala kumele ilayishwe kuma-write latches. Uchungechunge oluyisisekelo lwe-RTSP ukusetha i-Table Pointer, i-TBLPAG register, bese wenza uchungechunge lwemiyalelo ye-TBLWT ukulayisha ama-write latches. Ukuhlela kwenziwa ngokubeka ama-control bits ku-NVMCON register. Inani lemiyalelo ye-TBLWTL kanye ne-TBLWTH edingekayo ukulayisha ama-write latches lilingana nenani lamagama ohlelo okufanele abhalwe.
