1、个人收集整理仅供参考学习PINNAMEDESCRIPTIONTYPENormalVoltageStatusHighMinLevelHighMaxLevelActiveProgramBNR#(BlockNextRequest)若busagent無法接受新的transactions時Active此訊號.,使目前busowner不要在發新transactions.I/OHigh(1.5V)0.8V1.2V開機時,Winstoen99/NTDBSY#(DataBusBusy)訊號被定義時,表示匯流排正被使用中.I/OHigh(1.5V)0.8
2、V1.2V開機時,Winstoen99/NTDEFER#指出資料轉換不能很確定的依順序完成.IHigh(1.5V)0.8V1.2V開機時,Winstoen99/NTDRDY#(DataReady)資料傳輸時,此訊號暗指匯流排(databus)已準被好了,等待傳輸.I/OHigh(1.5V)0.8V1.2V開機時,Winstoen99/NTFERR#(Floating-pointError)當浮點運算錯誤時.此訊號將Active.此訊號與intel387處理器ERROR#訊號類似.OHigh(1.5V)0.8V1.2VRunDIVZ.E
3、XEHIT#(SnoopHIT)Snoopphase時cacheingagent保有未修改之資料此時會Active.I/OHigh(1.5V)0.8V1.2V開機時,Winstoen99/NTHITM#(HitModified)同HIT#資料有更改時此訊號為active.I/OHigh(1.5V)0.8V1.2V開機時,Winstoen99/NTINIT#(Initialization)當此訊號被定義,重置處理器內之整數暫存器,並且不改變(L1,L2)快取caches或浮點暫存器,IHigh(1.5V)0.8V1.2VNT=>Shut
4、down=>ResetLOCK#LOCK#Active時此transactions為不可分割的.I/OHigh(1.5V)0.8V1.2V開機時可trigger到SLP#(Sleep)Active時處理器會處於Sleepstate.IHigh(1.5V)0.8V1.2V進入Stangby个人收集整理仅供参考学习STPCLK#(StopClock)此訊號Active時處理器會處於lowpowerStop-Grantstate而且停止處理器的內部的時脈,此為一非同步的訊號.IHigh(1.5V)0.8V1.2V進入StangbySMI#(
5、SystemManagementInterrupt)此系統被保存於SystemManagementMode,當SMI被Active時,處理器從SMM開使執行程式.IHigh(1.5V)0.8V1.2V開機時,使用USBKeyboard使其有按鍵動作LINT0/INTR(InterruptRequest)中斷需求OLow(0V)0.8V1.2V開機時,Winstoen99/NTFreuenctMultipiers=2.5LINT1/NMI(Non-Maskable-Interrupt)不可遮罩中斷OLow(0V)0.8V1.2VFreu
6、enctMultipiers=6CPURST#Active時處理器將clearL1,L2caches內容.並進入可知狀態.IHigh(1.5V)0.8V1.2V按HardwareReset,或開機時A20M#(Address-20Mask)RUN8086的定址模式,addresswarp-aroundatthe1-Mbyteboundary.IHigh(1.5V)0.8V1.2VFreuenctMultipiers=4IGNNE#(IgnoreNumericError)使處理器忽視數值錯誤.,繼續執行數值運算,IHigh(1.5V)0
7、.8V1.2VFreuenctMultipiers=3RunDIVZ.exeHD[0…63]Data64-bitsignalI/OHigh/Low0.8V1.2V開機時,Winstoen99/NTHA[3…31]Address64-bitsignalI/OHigh/Low0.8V1.2V開機時,Winstoen99/nyVID[0…3](VoltageID)不是訊號,為0or1組合定義提供處理器的電壓值OHigh/Low0.8V2.0VRS[0…2](ResponseStatus)此訊號將會回應Transactions執行的狀態與結果
8、.IHigh/Low0.8V1.2V開機時,Winstoen99/NTREQ[0…4](Request)當處理器要Request會發command給chipset.I/OHigh/Low0.8V1.2V開機時,Winst
