15.7.6 UART n Interrupt Identification register (UARTn_II) (n=0,1,2,3)
Address Offset: 0x08
This register provides a status code that denotes the priority and source of a pending interrupt.
The interrupts are frozen during a UARTn_II register access. If an interrupt occurs during a UARTn_II register access,
the interrupt is recorded for the next UARTn_II register access.
