  1. 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.
