Interrupt acknowledge is the process of acknowledging a hardware interrupt, obtaining an interrupt vector address, and initiating the interrupt service routine in software. The INTA- (Interrupt Acknowledge) pin has the same timing as RD-, and external hardware is expected to provide an opcode in response to it. In the case of TRAP, RST7.5, RST6.5, and RST5.5, there is no specific interrupt acknowledge cycle like there is for INTR, but everything else is the same.

What is the function of interrupt acknowledge pin in 8085 micro processor?
The INTA- (Interrupt Acknowledge) pin on the 8085 is an acknowledge of the INTR (Interrupt Request). It has the same timing as RD-, and external hardware is expected to provide an opcode, usually a CALL or an RST instruction, in response to INTA-.
What is the meaning of INTA pin?
INTA stands for interrupt acknowledge. When it goes low, it asks the external device to get ready to place the type number onto the data bus. One device sends the interrupt request to the other device and when the other device is ready to accept that request , it sends the interrupt acknowledge to the device.
What does the acronym INTA stand for?
One of the things that the acronym INTA stands for is the International Trademark Association. Another thing that it can stand for is Interrupt Acknowledge.
When an IRET instruction is executed what action takes place?
By ABDULLAH ABID Secretary Info & IT GLOBAL PEACE COUNCIL PAKISTAN. http://h.1asphost.com/gpcp/org The Interrupt-In-Service-Flag is set at the beginning of an interrupt-acknowledge cycle. It is reset by the IRET (Interrupt-RETurn) instruction. When IIS is set, interrupts are disabled. When the Status-register is read, IIS always reads as '0'.
What part of speech is interrupt?
Interrupt is a verb.
What is the use of interrupt vector?
An interrupt vector is the memory address of an interrupt handler, or an index into an array called an interrupt vector table or dispatch table. Interrupt vector tables contain the memory addresses of interrupt handlers. When an interrupt is generated, the processor saves its execution state via a context switch, and begins execution of the interrupt handler at the interrupt vector.
What is a sentence with the word interrupt?
"You should not interrupt class," the teacher scolded the boy.
What is the Prefix of interrupt?
the prefix of interrupt is in
What is the prefix for interrupt?
The prefix for interrupt is "inter-".
Where is interrupt handler and interrupt vector?
In the 8086/8088, the interrupt vector table is the first 1024 bytes of memory. In the 8085, the interrupt vector table is the first 64 bytes of memory if using the RST form of interrupt, otherwise the interrupt vector is provided by the interrupting device, usually in the form of a CALL instruction. The interrupt handler is wherever the interrupt vector points to.
What is an 8085 interrupt?
There are 2 types interrupts in 8085 such as: 1)hardware interrupt 2)software interrupt
What is the noun form interrupt?
