Which are vectored interrupt?
In a computer, a vectored interrupt is an I/O interrupt that tells the part of the computer that handles I/O interrupts at the hardware level that a request for attention from an I/O device has been received and and also identifies the device that sent the request.
What are vectored interrupts with example?
They are – RST 0, RST 1, RST 2, RST 3, RST 4, RST 5, RST 6, RST 7. Vectored Interrupts are those which have fixed vector address (starting address of sub-routine) and after executing these, program control is transferred to that address. INTR is the only non-vectored interrupt in 8085 microprocessor.
What are vectored and non vectored interrupts?
Vectored Interrupts are those which have fixed vector address (starting address of sub-routine) and after executing these, program control is transferred to that address. Non-Vectored Interrupts (Scalar Interrupt) are those in which vector address is not predefined.
What is the difference between polling and vectored interrupt system?
There are two common ways in which buses implement interrupts: vectored and polled. Both methods commonly supply a bus-interrupt priority level. However, vectored devices also supply an interrupt vector; polled devices do not.
How many vectored interrupts are there in 8051?
5 interrupt signals
8051 has 5 interrupt signals, i.e. INT0, TFO, INT1, TF1, RI/TI….IP (Interrupt Priority) Register.
| – | IP.6 | Reserved for future use. |
|---|---|---|
| – | IP.5 | Reserved for future use. |
| PS | IP.4 | It defines the serial port interrupt priority level. |
What is maskable and non maskable interrupt in 8051?
Maskable interrupt is a hardware Interrupt that can be disabled or ignored by the instructions of CPU. A non-maskable interrupt is a hardware interrupt that cannot be disabled or ignored by the instructions of CPU.
