ʻO MICROCHIP DMT ʻO ka manawa make
Nānā: Ua manaʻo ʻia kēia ʻāpana manual reference no ka hoʻokō ʻana i nā pepa ʻikepili. Ma muli o ka ʻano mea like ʻole, ʻaʻole pili kēia ʻāpana manual i nā mea hana dsPIC33/PIC24 āpau.
- E ʻoluʻolu e nānā i ka memo ma ka hoʻomaka o ka mokuna "Deadman Timer (DMT)" ma ka pepa ʻikepili o kēia manawa e nānā inā kākoʻo kēia palapala i ka mea āu e hoʻohana nei.

OLELO HOOLAHA
Hoʻolālā ʻia ka module Deadman Timer (DMT) i mea e hiki ai i nā mea hoʻohana ke nānā i ke olakino o kā lākou polokalamu noi ma o ka koi ʻana i nā manawa hoʻopau manawa i loko o ka pukaaniani manawa i kuhikuhi ʻia e ka mea hoʻohana. ʻO ka module DMT he counter synchronous a inā hiki, helu i nā kiʻi aʻo, a hiki ke hana i kahi pahele palupalu. E nānā i ka mokuna "Interrupt Controller" ma ka pepa ʻikepili o kēia manawa e nānā inā he pahele palupalu ka hanana DMT inā ʻaʻole holoi ʻia ka counter DMT i loko o kahi helu o nā kuhikuhi. Hoʻopili maʻamau ka DMT i ka uaki ʻōnaehana e hoʻokele i ka mea hana (TCY). Hōʻike ka mea hoʻohana i ka waiwai manawa manawa a me kahi waiwai mask e kuhikuhi ana i ka laulā o ka puka makani, ʻo ia ka laulā o nā helu i manaʻo ʻole ʻia no ka hanana hoʻohālikelike.
ʻO kekahi o nā hiʻohiʻona nui o kēia module:
- Hiki ke hoʻomalu ʻia ka hoʻonohonoho ʻana a i ʻole ka lako polokalamu
- ʻO ka manawa hoʻomaha a i ʻole ka helu ʻōlelo a ka mea hoʻohana
- ʻElua mau kaʻina aʻo e hoʻomaʻemaʻe i ka manawa
- 32-bit configurable window e holoi i ka manawa
hōʻike i kahi kiʻina poloka o ka module Deadman Timer.
ʻO ke kiʻikuʻi poloka ʻo Deadman Timer Module
Nānā:
- Hiki ke hoʻohana ʻia ka DMT ma ka papa inoa Configuration, FDMT, a i ʻole ma ka Special Function Register (SFR), DMTCON.
- Hoʻopaʻa ʻia ka DMT i kēlā me kēia manawa e kiʻi ʻia nā ʻōlelo aʻo e ka mea hana me ka hoʻohana ʻana i ka uaki ʻōnaehana. No exampma hope o ka hoʻokō ʻana i kahi ʻōlelo aʻo GOTO (e hoʻohana ana i ʻehā mau ʻōkuhi aʻo), e hoʻonui ʻia ka counter DMT i hoʻokahi wale nō.
- ʻO BAD1 a me BAD2 nā hae kaʻina kūpono ʻole. No ka ʻike hou aku, e nānā i ka Pauku 3.5 "Hoʻoponopono hou i ka DMT".
- Hoʻomalu ʻia ka DMT Max Count e ka waiwai mua o nā papa inoa FDMTCNL a me FDMTCNH.
- ʻO kahi hanana DMT he pahele palupalu hiki ʻole ke uhi ʻia.
hōʻike i ke kiʻikuhi manawa o kahi hanana Deadman Timer.

Aia ka module DMT me kahi counter 32-bit, ka heluhelu-wale DMTNTL a me DMTCNH nā papa inoa me ka helu helu manawa-waho, e like me ka mea i kuhikuhi ʻia e nā papa inoa ʻelua o waho, 16-bit Configuration Fuse registers, FDMTCNTL a me FDMTCNTH. I kēlā me kēia manawa e loaʻa ai ka pāʻani helu, hiki mai kahi hanana DMT, ʻaʻole ia he pahele palupalu. E nānā i ka mokuna "Interrupt Controller" ma ka pepa ʻikepili o kēia manawa e nānā inā he pahele palupalu ka hanana DMT. Hoʻohana maʻamau ʻia kahi module DMT i nā noi koʻikoʻi a me ka palekana, kahi e ʻike ʻia ai kekahi hemahema o ka hana a me ka hoʻonohonoho ʻana.
E ho'ā ana a hoʻopau i ka Module DMT
Hiki ke hoʻohana ʻia a hoʻopau ʻia ka module DMT e ka hoʻonohonoho hoʻonohonoho ʻana a i ʻole hiki ke hoʻohana ʻia ma o ka lako polokalamu ma ke kākau ʻana i ka papa inoa DMTCON.
Inā hoʻonohonoho ʻia ka bit Configuration DMTEN ma ka papa inoa FDMT, hiki ke hoʻohana mau ʻia ka DMT. Na ka ON control bit (DMTCON[15]) e hōʻike i kēia ma ka heluhelu ʻana i kahi '1'. Ma kēia ʻano, ʻaʻole hiki ke holoi ʻia ka bit ON i ka lako polokalamu. No ka hoʻopau ʻana i ka DMT, pono e kākau hou ʻia ka hoʻonohonoho ʻana i ka hāmeʻa. Inā hoʻonoho ʻia ʻo DMTEN i '0' i loko o ka fuse, a laila pio ka DMT i ka lako.
Hiki i ka lako polokalamu ke hoʻohana i ka DMT ma ka hoʻonohonoho ʻana i ka bit ON ma ka papa inoa Deadman Timer Control (DMTCON). Eia naʻe, no ka hoʻomalu polokalamu, pono e hoʻonohonoho ʻia ka bit Configuration DMTEN ma ka papa inoa FDMT i '0'. Ke hoʻohana ʻia, ʻaʻole hiki ke hoʻopau i ka DMT i ka lako polokalamu.

Loaʻa i ka module DMT kahi ʻano hana Windowed. ʻO ka DMTIVT[15:0] a me DMTIVT[31:16] ʻO nā ʻāpana hoʻonohonoho i loko o nā FDMTIVTL a me FDMTIVTH papa inoa, e hoʻonohonoho i ka waiwai inter-val pukaaniani. Ma ke ʻano Windowed, hiki i ka polokalamu ke hoʻomaʻemaʻe i ka DMT wale nō ke kū ka counter i kona puka makani hope ma mua o ka hiki ʻana o kahi helu helu. ʻO ia hoʻi, inā ʻoi aku ka nui o ka helu counter DMT ma mua a i ʻole like me ka waiwai i kākau ʻia i ka waiwai waena puka makani, a laila hiki ke hoʻokomo ʻia ke kaʻina akaka i loko o ka module DMT. Inā hoʻomaʻemaʻe ʻia ka DMT ma mua o ka puka aniani i ʻae ʻia, hoʻopuka koke ʻia kahi pahele palupalu Deadman Timer a i ʻole hoʻopau.
ʻO ka hana DMT ma nā ʻano hoʻōla mana
Ma muli o ka hoʻonui ʻia ʻana o ka module DMT e nā kiʻi ʻōlelo aʻo, ʻaʻole e loli ka helu helu ke hana ʻole ke kumu. ʻAʻole paʻa ka module DMT i nā ʻano moe a me nā ʻano Idle. Ke ala aʻe ka hāmeʻa mai Sleep a i ʻole Idle, hoʻomaka hou ka helu DMT e hoʻonui.
Hoʻoponopono hou i ka DMT
Hiki ke hoʻonohonoho hou ʻia ka DMT ma nā ʻano ʻelua: ʻo ke ala hoʻokahi e hoʻohana ana i kahi ʻōnaehana Reset a ʻo kahi ala ʻē aʻe ma ke kākau ʻana i kahi kaʻina i kauoha ʻia i ka DMTPRECLR a me ka DMTCLR registers. Pono ka hoʻomaʻemaʻe ʻana i ka waiwai counter DMT i kahi kaʻina hana kūikawā:
- Pono e kākau ʻia nā ʻāpana STEP1[7:0] ma ka papa inoa DMTPRECLR e like me '01000000' (0x40):
- Inā kākau ʻia kekahi waiwai ʻē aʻe ma mua o 0x40 i nā bits STEP1x, e hoʻonohonoho ʻia ka bit BAD1 ma ka papa inoa DMTSTAT a hoʻomaka ia i kahi hanana DMT.
- Inā ʻaʻole ma mua o ka ʻanuʻu 2 e ka ʻanuʻu 1, ua hoʻonohonoho ʻia nā hae BAD1 a me DMTEVENT. Hoʻomaʻemaʻe wale ʻia nā hae BAD1 a me DMTEVENT ma kahi hāmeʻa Reset.

Ke kākau ʻia nā waiwai kūpono, e holoi ʻia ka counter DMT i ka ʻole. E hoʻomaʻemaʻe ʻia ka waiwai o ka DMTPRECLR, DMTCLR a me DMTSTAT kakau inoa 'ole.

- ʻAʻole hoʻokō ʻia ka ʻanuʻu 2 ma ka puka makani ākea; ke kumu e kau ai ka hae BAD2. Hiki koke mai kahi hanana DMT.
- ʻO ke kākau ʻana i nā kaʻina hoʻomaʻamaʻa mua (0x40) e hoʻonohonoho ʻia ka hae BAD2 a hoʻokumu i kahi hanana DMT.
Nānā: Ma hope o ke kaʻina preclear/akaka hewa ʻole, pono e hoʻonohonoho i ka hae BAD1/BAD2 a ma kahi liʻiliʻi e hoʻonohonoho i ka DMTEVENT.
Hoʻomaʻemaʻe wale ʻia nā hae BAD2 a me DMTEVENT ma kahi hāmeʻa Reset. E nānā i ka papa kuhikuhi holoʻokoʻa e like me ka mea i hōʻike ʻia ma ke Kiʻi 3-1.
