- Pe a ulu atu se tuusaunoaga po o le faalavelave, e otometi lava ona faafou e le microprocessor le tusi resitala CSR talafeagai, e aofia ai le masini tulaga tuusaunoaga mafuaaga resitara mcause, le masini tulaga tuusaunoaga pointer resitara mepc, le masini masini tulaga tuusaunoaga resitala uʻamea, ma le masini tulaga tulaga resitala tulaga.

Fa'afou mcause

E pei ona taʻua muamua, pe a uma ona ulufale i se tuusaunoaga poʻo se faʻalavelave, o lona tau e atagia mai ai le ituaiga tuusaunoaga o loʻo i ai nei poʻo le numera faʻalavelave, ma e mafai e le polokalama faʻapipiʻi ona faitau le tau o le resitala e siaki ai le mafuaʻaga o le faʻalavelave poʻo le fuafuaina o le puna o le faʻalavelave, e pei ona auiliiliina i le Laulau 2 -1.

Fa'afou mepc

O le faʻamatalaga masani o le tuatusi faʻafoʻi o le microprocessor pe a uma ona alu ese mai se tuusaunoaga poʻo faʻalavelave o loʻo teuina i le mepc.

O lea la pe a tupu se tuusaunoaga poʻo se faʻalavelave, e otometi lava ona faʻafouina e le masini le tau o le mepc i le faʻatonuga o loʻo i ai nei PC pe a oʻo i le faʻalavelave, poʻo le isi faʻatonuga muamua aʻo leʻi faʻalavelaveina.
A mae'a ona fa'agasolo le fa'alavelave po'o le fa'alavelave, e fa'aaoga e le microprocessor lona tau fa'asaoina e fai ma tuatusi toe fo'i atu i le nofoaga o le fa'alavelave e fa'aauau ai le fa'atinoga.
Ae ui i lea, e taua le matauina o lena mea.

MEPC o se tusi resitala e mafai ona faitau ma tusitusi, ma e mafai foi e le polokalama faakomepiuta ona suia le tau e sui ai le nofoaga o le PC pointer o loʻo tamoe pe a uma le toe foʻi mai.
Pe a tupu se faʻalavelave, o lona uiga, pe a faʻamaonia le mafuaʻaga o le mcause[31]=1, o le tau o faʻafanua e faʻafouina i le tau PC o le isi faʻatonuga e leʻi faia i le taimi o le faʻalavelave.
- Pe a tupu se tuusaunoaga, o le tau o faafanua e toe faafou i le aoga o le PC o le tuusaunoaga o loo i ai nei pe a o le tuusaunoaga e mafua ai le resitala mcause[31]=0. O lea la i le taimi nei pe a toe foʻi mai le tuusaunoaga, afai tatou te toe foʻi saʻo e faʻaaoga ai le tau o le mepc, tatou te faʻaauau pea ona faʻatinoina le faʻatonuga na mafua ai le tuusaunoaga muamua, ma i le taimi nei, o le a tatou faʻaauau pea ona ulufale i le tuusaunoaga. E masani lava, a uma ona tatou taulimaina le tuusaunoaga, e mafai ona tatou suia le tau o le mepc i le tau o le isi faatonuga e leʻi faia ona toe foʻi mai lea. Mo example, afai tatou te mafua ai se tuusaunoaga ona o le valaau / motusia, pe a uma ona taulimaina le tuusaunoaga, talu ai manatua / malologa (c.ebreak o 2 bytes) o se faatonuga 4-byte, tatou te manaomia le polokalama e suia le tau o le mepc i le mepc +4 (c.ebreak is mepc+2) ona toe foʻi mai lea.

Fa'afou mtval

A o'o ina fa'aulu mai fa'alavelave ma fa'alavelave, e otometi lava ona fa'afouina e meafaigaluega le tau o le mtval, o le tau lea na mafua ai le fa'alavelave. O le tau e masani lava.

Afai o se tuusaunoaga e mafua mai i se avanoa e manatua ai, o meafaigaluega o le a teuina le tuatusi o le manatua avanoa i le taimi o le tuusaunoaga i mtval.

Afai o le tuusaunoaga e mafua mai i se faatonuga e le tusa ai ma le tulafono, o le meafaigaluega o le a teuina le tulafono o faatonuga o le faatonuga i le mtval.
Afai o le tuusaunoaga e mafua mai i se mea e motu ai meafaigaluega, o le a teuina e le masini le tau o le PC i le vaeluaga i le mtval.
Mo isi tuusaunoaga, o meafaigaluega e setiina le tau o le mtval i le 0, e pei o le malologa, o le tuusaunoaga e mafua mai i faatonuga valaau.

Pe a ulufale i le faʻalavelave, e setiina e meafaigaluega le tau o le mtval i le 0.

Fa'afou mstatus

I le ulufale atu i tuusaunoaga ma faʻalavelave, e faʻafouina e le meafaigaluega nisi vaega i le mstatus.

O le MPIE e fa'afou i le tau MIE a'o le'i ulufale i le tuusaunoaga po o le fa'alavelave, ma o le MPIE e fa'aaogaina e toe fa'afo'i ai le MIE pe a uma le tuusaunoaga ma fa'alavelave.
O le MPP e fa'afouina i le tulaga fa'apitoa a'o le'i ulufale i tuusaunoaga ma fa'alavelave, ma a mae'a fa'alavelave ma fa'alavelave, e fa'aaoga le MPP e toe fa'afo'i ai le tulaga fa'apitoa muamua.
QingKe V3 microprocessor e lagolagoina fa'alavelave faamoega i le masini, ma ole MIE ole a le kilia pe a uma ona ulufale tuusaunoaga ma faalavelave.

Fa'afou tulaga fa'apitoa microprocessor

A tula'i mai fa'alavelave ma fa'alavelave, e fa'afou le faiga fa'apitoa o le microprocessor i le masini.

Galuega Fa'atino Fa'apitoa

I le ulufale atu i se tuusaunoaga poʻo le faʻalavelave, e faʻatino e le microprocessor le polokalame mai le tuatusi ma le faʻaogaina o loʻo faʻamatalaina e le resitala mtvec. Pe a faʻaaogaina le faʻasalalauga tuʻufaʻatasia, e ave e le microprocessor se faʻatonuga oso mai le tuatusi autu o loʻo faʻamatalaina e mtvec [31: 2] faʻavae i luga o le tau o le mtvec [1], poʻo le mauaina o se tuusaunoaga ma faʻalavelave le faʻaogaina o le tuatusi o le galuega ma alu e faʻatino nai lo lena. . I le taimi nei, o le tuusaunoaga ma le faʻalavelave faʻaogaina galuega e mafai ona iloa pe o le mafuaʻaga o se tuusaunoaga poʻo se faʻalavelave e faʻavae i luga o le tau o le mcause[31], ma o le ituaiga ma le mafuaʻaga o le tuusaunoaga poʻo le faʻalavelave tutusa e mafai ona faʻamasinoina e le code tuusaunoaga. ma taulimaina e tusa ai.
Pe a faʻaaogaina le tuatusi faʻavae + numera faʻalavelave *4 mo le faʻamalo, e otometi lava ona oso le meafaigaluega i le laulau vector e maua ai le tuatusi ulufale o le tuusaunoaga poʻo le faʻalavelave faʻavae e faʻavae i luga o le numera faʻalavelave ma oso e faʻatino.

Tuusaunoaga Ulufafo
