The UIIRs indicate when an interrupt is pending from the corresponding UART and what type of interrupt
is active. They also indicate if the FIFOs are enabled.
The DUART prioritizes interrupts into four levels and records these in the corresponding UIIR. The four
levels of interrupt conditions in order of priority are:
