Parallel Connection Priority Interrupt || Lesson 86 || Computer Organization || Learning Monkey ||

Here we will understand Parallel Connection Priority Interrupt.
The parallel priority interrupt method uses a register whose bits are set separately
by the interrupt signal from each device. Priority is established according
to the position of the bits in the register. In addition to the interrupt register,
the circuit may include a mask register whose purpose is to control the status
of each interrupt request. The mask register can be programmed to disable lower-priority interrupts while a higher-priority device is being serviced. It can
also provide a facility that allows a high-priority device to interrupt the CPU
while a lower-priority device is being serviced.
