UART Interrupt Identification Register
The Read Only UARTx_IIR register allows the user to check whether the FIFO is enabled
and the status of interrupts. These registers share the same I/O addresses as the
UARTx_FCTL registers. See
Table 57. UART Interrupt Identification Registers(UART0_IIR = 00C2h, UART1_IIR =
Table 58. UART Interrupt Status Codes

Description
FIFO is disabled.
Receive FIFO is disabled (MULTIDROP mode).
FIFO is enabled.
Reserved.
Interrupt Status Code
The code indicated in these three bits is valid only if INTBIT is
1. If two internal interrupt sources are active and their
respective enable bits are High, only the higher priority
interrupt is seen by the application. The lower-priority interrupt
code is indicated only after the higher-priority interrupt is
serviced.
There is an active interrupt source within the UART.
There is not an active interrupt source within the UART.
