WebJul 24, 2024 · Sorted by: 3. CR8 indicates the current priority of the CPU. When an interrupt is pending, bits 7:4 of the interrupt vector number is compared to CR8. If the vector is greater, it is serviced, otherwise it is held pending until CR8 is set to a lower value. Assuming the APIC is in use, it has an IRR (Interrupt Request Register) with one bit per ... WebAug 10, 2024 · The priority registers is only 8-bits and will only implement a few bits of the 8-bit register, so presumably when the value gets shifted you are not ending up with any bits set in any of the bits implemented by the hardware, so the value will appear to the hardware as 0. ...
