Question: During processor multiplexing using interrupts and the interval timer, the processor receives a timer interrupt when the interrupt request flag (interruptRequest) is set to TRUE

During processor multiplexing using interrupts and the interval timer, the processor receives a timer interrupt when the interrupt request flag (interruptRequest) is set to TRUE by the interval timer device. In the discussion, it is assumed that the interrupt software will reset interruptRequest to FALSE when it processes the interrupt. What would happen if the interval timer interrupt software reset the flag, but another interrupt occurred before the interval timer interrupt routine and scheduler completed their work?
