Whakaahuatanga
Ko te AT91SAM9261 he punaha-i-kiripi oti i hangaia huri noa i te ARM926EJ-S ARM Thumb tukatuka me te huinga tohutohu DSP roa me te Jazelle Java whakatere.Ka tutuki te 210 MIPS i te 190 MHz.Ko te AT91SAM9261 he pūtukatuka manaaki pai mo nga tono me te whakaaturanga LCD.Ko tana kaiwhakahaere LCD whakauru e tautoko ana i te BW tae atu ki te 16M te tae, nga whakaaturanga LCD hohe me te wahangu.Ko te 160 Kbyte integrated SRAM ka taea te whirihora hei parepare anga e whakaiti ana i te paanga mo te whakahou LCD i runga i te mahinga tukatuka katoa.Ko te Atanga Pahi o waho kei te whakauru i nga kaiwhakahaere mo te DRAM tukutahi (SDRAM) me nga maharatanga Static me te whakaatu i te ara iahiko atanga motuhake mo te CompactFlash me te NAND Flash.Ko te AT91SAM9261 he whakauru i tetahi Boot Loader-a-ROM e tautoko ana i te waehere marumaru mai, hei tauira, DataFlash® waho ki SDRAM waho.Ko te Kaiwhakahaere Whakahaere Hiko (PMC) e whakahaeretia ana e te rorohiko e pupuri ana i te iti o te kohi hiko o te punaha ma te whakaahei/whakakore i te tukatuka me nga momo peripheral me te whakatikatika i te auau whakahaere.Ka whai hua ano te AT91SAM9261 mai i te whakaurunga o te whānuitanga o nga ahuatanga patuiro tae atu ki a JTAG-ICE, he hongere patuiro UART (DBGU) i whakatapua me tetahi tohu wa tuturu.Ma tenei ka taea te whakawhanaketanga me te patuiro o nga tono katoa, ina koa ko nga mea e herea ana i te waa.
