What is method to disable all the interrupts?

To disable all interrupts, either the Global Interrupt Enable (GIE) bit must be cleared or all the individual interrupt enable bits must be cleared. An issue arises when an instruction clears the GIE bit and an interrupt occurs “simultaneously”.

How do I enable and disable interrupts in Arduino?

If you wish to disable interrupts (when executing some critical piece of code, especially one which should be completed within a given time period), you can do that with the help of the noInterrupts() function.

How do I enable and disable an interrupt?

Assuming that interrupts are enabled, the following is a typical scenario:

1. The device raises an interrupt request.
2. The processor interrupts the program currently being executed.
3. Interrupts are disabled by changing the control bits in the PS (except in the case of edgetriggered interrupts).

Which is disable interrupt?

When entering an inteerupt handler, we first “disable interrupts” on that cpu(using something like the cli instruction on x86). During the time that interrupts are disabled, assume say the user pressed the letter ‘a’ on the keyboard that would usually cause an interrupt.

When if interrupt flag is disabled following is true?

If a trigger flag is set, but the interrupts are disabled (I=1), the interrupt level is not high enough, or the flag is disarmed, the request is not dismissed. Rather the request is held pending, postponed until a later time, when the system deems it convenient to handle the requests.

Can the interrupt process be disabled?

(Obvious answer): The process is allowed to run while interrupts are disabled since clearly this is what the code is intended to do.
