The U1IIR provides a status code that denotes the priority and source of a pending
interrupt. The interrupts are frozen during an U1IIR access. If an interrupt occurs during
an U1IIR access, the interrupt is recorded for the next U1IIR access.
Bit U1IIR[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
Enables the end of auto-baud interrupt.
Disable end of auto-baud Interrupt.
Enable end of auto-baud Interrupt.
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.
Interrupt status. Note that U1IIR[0] is active low. The pending interrupt can be
determined by evaluating U1IIR[3:1].
At least one interrupt is pending.
No interrupt is pending.
Interrupt identification. U1IER[3:1] identifies an interrupt corresponding to the
UART1 Rx or TX FIFO. All other combinations of U1IER[3:1] not listed below
are reserved (100,101,111).
1 - Receive Line Status (RLS).
2a - Receive Data Available (RDA).
2b - Character Time-out Indicator (CTI).
3 - THRE Interrupt.
4 - Modem Interrupt.
Reserved, user software should not write ones to reserved bits. The value read
from a reserved bit is not defined.
Copies of U1FCR[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, the value read from a reserved bit is not defined.
