. Interrupt Controller (INTC) Algorithm and Programming [2-part question]:

a. Write the low-level algorithm and ARM assembly to unmask IRQ interrupts for

UART3 in the INTC.

b.

Write the low-level algorithm and ARM assembly to check if an IRQ is from UART3

in the INTC. You can assume that some sort of IRQ happened and the PC is now in

the INT_DIRECTOR section of the code. If the interrupt is from UART3, you should

branch to a label named UART_HANDLER. If it is not from UART3, you should

branch to a label named PASS_ON. Your code should prepare the INTC for the

next interrupt if the current interrupt was from UART3. You dont need to do

anything with the UART module, this problem is only about how you interact with

the INTC to check for interrupts.
