What else can I help you with?
How many interrupt lines does 8086 have?
8086 have 5 interrupt lines.
Is rst7.5 is a maskable interrupt in 8086?
No. RST7.5 is a maskable interrupt on the 8085, not the 8086/8088.
Is masked Kane and Kane the same?
yes Kane masked and unmasked are same
How 8086 responds to an interrupt?
When the 8086 microprocessor receives an interrupt signal, it completes the execution of the current instruction and saves the address of the next instruction onto the stack. It then determines the appropriate interrupt vector from the Interrupt Vector Table (IVT) based on the interrupt type. The processor then transfers control to the interrupt service routine (ISR) associated with that interrupt. After the ISR has executed, the 8086 retrieves the saved address from the stack and resumes execution from where it was interrupted.
What do you mean by IVT in 8086?
Interrupt vector table
What is Bios function call in 8086 microprocessor?
The BIOS function in the 8086 microprocessor is called an interrupt function. It is an interrupt function because it is not called by a function call instruction.
What is the size of the interrupt vector table in the 8086-8088 microprocessor?
There are 256 different interrupt vectors in the 8086/8088. Each vector is a far CS:IP address, which is four bytes. That makes the interrupt vector table 1,024 bytes.
What is physical starting address and ending address of interrupt vector table of 8086?
The 8086 interrupt table is from 0000h to 03FFh for interrupt 0 through interrupt 255. It is common practice to design systems that use only the lower-numbered interrupts and then use the upper part of the interrupt table for code or data. For more information see: http://datasheets.chipdb.org/Intel/x86/808x/datashts/8086/231455-005.pdf
Which type of interrupt can not be masked by software?
The TRAP interrupt can not be masked by software, unless there is hardware in place to allow that, perhaps by anding an output bit with the TRAP request line.
What coler is Kane's face?
masked is black and unmasked dosent have hair
What is INTA in 8086 in miscropress?
Interrupt Acknowledgegenerated by the microprocessor in response to INTR. Causes the interrupt vector to be put onto the data bus
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.
