Bog'liq RGqpeVcTGrACPEqq2WlPDTbgx7NbOwBBfRKOuADM(1)NMI kirishi INTR kirishiga qaraganda yuqori ustivorlikka ega. Кроме того, вход NMI не маскируется, а вход INTR маскируется маской прерываний IF из регистра признаков ЦП.
Shuning uchun, apparatli (tashqi) uzilishlar ikki turga bo’linadi: maskalanadigan va maskalanmaydigan.
Internal interruptions .
Rejection _ type interruption ( fault ) - occurs in the case, when in the conclusion of various shortcomings nevozmojno normalnoe execution of the command - interruption occurs before the execution of the command.
" Trap " break ( trap ) - of the command completion as a result to the surface comes , for example , INT N delay command .
« Commands emergency termination » abortion equipment _ _ _ in error to the surface is coming . It 's kind of interruptions not masked .
" Error " type interruptions - different kind of errors as a result of the command normal completion possible not cases to the surface coming - delay command from completion before happen will be .
Ichki uzilishlar.
Rad qilish turidagi uzilish (fault) –наступает в случаях, когда в результате различных некорректностей невозможно нормальное выполнение команды – прерывание наступает до выполнения команды.
«tuzoq» uzilish (trap) – buyruqning bajarilishi natijasida yuzaga keladi, masalan, INT N uzilish buyrug’i.
«buyruqlarni favqulotda to’xtatish» uzilish (abort) apparaturalar xatoligida yuzaga keladi. Bu turdagi uzilishlar maskalanmaydi.
"Xato" turidagi uzilishlar - turli xil xatolar natijasida buyruqning normal bajarilishi mumkin bo'lmagan holatlarda yuzaga keladi - uzilish buyruq bajarilishidan oldin sodir bo'ladi.
Interruptions service as follows instead is increased .
Next command address stack placed : CS ( basic address ), IP ( offset ) (2 words ) and RF flag dimensions ( third word ) and IF = 0, TF = 0 bits in the RF register of the MP processor throw will be sent .
Then external from the device or in MP yield which was interruptions vector (UV) N numbers on , separated from UV TX is obtained .
