FUNCTION DESCRIPTION

System Interface

• Chip ichi chili ndi mitundu iwiri ya mawonekedwe ndi MPU: basi 4-bit ndi 8-bit basi. Mabasi a 4-bit ndi 8-bit amasankhidwa ndi DL bit mu kaundula wa malangizo.

Mbendera Yotanganidwa (BF)

• Pamene BF = "High", imasonyeza kuti ntchito yamkati ikukonzedwa. Choncho panthawiyi, malangizo otsatirawa sangavomerezedwe.
• BF ikhoza kuwerengedwa, pamene RS = Low ndi R / W = High (Werengani Instruction Operation), kudzera pa doko la DB7. Musanapereke malangizo otsatirawa, onetsetsani kuti BF sipamwamba.

Kauntala (AC)

• Adilesi Yowerengera (AC) imasunga adilesi ya DDRAM/CGRAM, yotumizidwa kuchokera ku IR. Pambuyo polemba mu (kuwerenga kuchokera) DDRAM/CGRAM, AC imawonjezedwa (kuchepa) ndi 1.
• Pamene RS = "Low" ndi R / W = "High", AC akhoza kuwerengedwa kudzera DB0 - DB6 madoko.

Onetsani Data RAM (DDRAM)

• Masitolo a DDRAM amawonetsa data yopitilira 80 x 8 bits (zilembo 80). Adilesi ya DDRAM imayikidwa mu kauntala (AC) ngati nambala ya hexadecimal.

CGROM (Quracter Generator ROM)

• CGROM ili ndi 5 x 8 madontho 204 zilembo ndi 5 x 10 madontho 32 zilembo. CGROM ili ndi zilembo 204 za madontho 5 x 8.

CGRAM (Character Generator RAM)

• CGRAM ili ndi madontho mpaka 5 × 8, zilembo 8. Polemba mafonti ku CGRAM, zilembo zofotokozedwa ndi ogwiritsa ntchito zitha kugwiritsidwa ntchito.

Ubale pakati pa Maadiresi a CGRAM, Zizindikiro za Khalidwe (DDRAM), ndi Makhalidwe (Data ya CGRAM)

Ndemanga:

1. Ma code bits 0 mpaka 2 amagwirizana ndi CGRAM adilesi bits 3 mpaka 5 (3 bits: 8 mitundu).
2. CGRAM imayimba ma bits 0 mpaka 2 ndikuyika mzere wa mzere wa zilembo. Mzere wa 8 ndi malo a cholozera ndipo chiwonetsero chake chimapangidwa ndi zomveka OR ndi cholozera. Sungani deta ya mzere wa 8, wofanana ndi malo owonetsera cholozera, pa 0 monga chowonetsera cholozera. Ngati deta ya mzere wa 8 ndi 1, 1 pang'ono idzawunikira mzere wa 8 mosasamala kanthu za kukhalapo kwa cholozera.
3. Malo amizere ya zilembo amafanana ndi CGRAM data bits 0 mpaka 4 (bit 4 kukhala kumanzere).
4. Monga momwe tawonetsera mu Table, machitidwe a CGRAM amasankhidwa pamene ma code bits 4 mpaka 7 onse ali 0. Komabe, popeza code code bit 3 ilibe mphamvu, R display ex.ample pamwambapa akhoza kusankhidwa ndi kachidindo ka 00H kapena 08H.
5. 1 ya data ya CGRAM ikufanana ndi kusankha kowonetsera ndi 0 kwa osasankhidwa Sikuwonetsa zotsatira.

Cursor/Blink Control Circuit

Imawongolera cholozera / kuphethira ON / OFF pa cholozera.

Kufotokozera Malangizo

Lembani autilaini

• Kuti mugonjetse kusiyana kwa liwiro pakati pa wotchi yamkati ya S6A0069 ndi wotchi ya MPU, S6A0069 imagwira ntchito zamkati posunga zowongolera mumayendedwe ku IR kapena DR.
• Ntchito yamkati imatsimikiziridwa molingana ndi chizindikiro chochokera ku MPU, chopangidwa ndi kuwerenga / kulemba ndi basi ya data (Onani Table 7).

Malangizo akhoza kugawidwa kwambiri m'magulu anayi:

1. S6A0069 ntchito seti malangizo (khazikitsani njira zowonetsera, ikani utali wa data, etc.)
2. Malangizo oyika ma adilesi ku RAM yamkati
3. Malangizo otengera deta ndi RAM yamkati
4. Ena

• Adilesi ya RAM yamkati imachulukitsidwa kapena kuchepetsedwa ndi 1.
• Zindikirani: pakugwira ntchito mkati, mbendera yotanganidwa (DB7) imawerengedwa kuti "High".
• Kuwunika mbendera kumayenera kutsogozedwa ndi malangizo otsatirawa.
