The UnIIR provides a status code that denotes the priority and source of a pending
interrupt. The interrupts are frozen during an UnIIR access. If an interrupt occurs during
an UnIIR access, the interrupt is recorded for the next UnIIR access.
Bit UnIIR[9:8] are set by the auto-baud function and signal a time-out or end of auto-baud
condition. The auto-baud interrupt conditions are cleared by setting the corresponding
Clear bits in the Auto-baud Control Register.
If the IntStatus bit is 1 no interrupt is pending and the IntId bits will be zero. If the IntStatus
is 0, a non auto-baud interrupt is pending in which case the IntId bits identify the type of
interrupt and handling as described in
interrupt handler routine can determine the cause of the interrupt and how to clear the
active interrupt. The UnIIR must be read in order to clear the interrupt prior to exiting the
Interrupt Service Routine.

Interrupt status. Note that UnIIR[0] is active low. The pending interrupt can be
determined by evaluating UnIIR[3:1].
At least one interrupt is pending.
No interrupt is pending.
Interrupt identification. UnIER[3:1] identifies an interrupt corresponding to the
UARTn Rx or TX FIFO. All other combinations of UnIER[3:1] not listed below
are reserved (000,100,101,111).
1 - Receive Line Status (RLS).
2a - Receive Data Available (RDA).
2b - Character Time-out Indicator (CTI).
3 - THRE Interrupt
Reserved, user software should not write ones to reserved bits. The value read
from a reserved bit is not defined.
Copies of UnFCR[0].
End of auto-baud interrupt. True if auto-baud has finished successfully and
interrupt is enabled.
Auto-baud time-out interrupt. True if auto-baud has timed out and interrupt is
enabled.
Reserved, user software should not write ones to reserved bits. The value read
from a reserved bit is not defined.
Enables the auto-baud time-out interrupt.
Disable auto-baud time-out Interrupt.
Enable auto-baud time-out Interrupt.
Reserved, user software should not write ones to reserved bits. The value
read from a reserved bit is not defined.
