when interrupt occurs, the program counter content will stores into stack, an PC will load interrupt address for next instruction execution. ofter completion ISR process PC will retrieves the stack values and execution will be continued.

What is ISR in RTOS?

ISR stands for Interrupt Service Routine. In RTOS, an ISR is a special function that is invoked in response to an interrupt. ISRs handle time-sensitive tasks and allow the system to respond quickly to external events without delaying the execution of other tasks.


Why jump instruction is invariably written in the vectored location of an interrupt request?

An interrupt makes the processor to jump to a vectored location in memory where the ISR is written. By observing the vectored locations for various interrupt inputs of 8085, we know that there are only 4 or 8 bytes allocated for ISR. This memory space is not sufficient for writing any code to process an interrupt. So we write a jump instruction that makes the processor jump to a location in user memory and write the ISR starting from that location.Example: suppose there is an interrupt signal to 8085 at RST 6.5. The call location for RST 6.5 is 0034H. The address space available is 4 bytes. So if we write instruction jmp 2300H at 0034H, then we can write ISR in memory locations starting from 2300H.


What is the component of joint force development that entails collecting observations?

The component of joint force development that entails collecting observations is called intelligence, surveillance, and reconnaissance (ISR). This involves gathering information on the enemy, the environment, and other relevant factors to support decision-making and planning in military operations.


How can I make a grandfather clock work properly?

To make a grandfather clock work properly, you should ensure it is on a level surface, wind it regularly according to the manufacturer's instructions, and have it professionally serviced every few years to keep it in good working condition.


Is sphygmomanometer working?

To check if a sphygmomanometer is working, you can first ensure that it is properly calibrated and inflated according to the manufacturer's instructions. Once inflated, make sure that the dial or digital display is functioning correctly, displaying accurate blood pressure readings. If there are any irregularities with the readings or if the device is not functioning properly, it may need to be serviced or replaced.

What is interrupt status register?

An Interrupt Status Register (ISR) is a hardware register used in computer systems to indicate the status of various interrupt sources. It helps the processor determine which interrupt has occurred and needs to be serviced. By reading the ISR, the system can prioritize and manage multiple interrupts efficiently, ensuring that higher-priority tasks are addressed promptly. This register is crucial for real-time processing and efficient multitasking in operating systems.
