SC16C754B
5 V, 3.3 V and 2.5 V quad UART, 5 Mbit/s (max.) with 64-byte FIFOs
6.5 Interrupts
The SC16C754B has interrupt generation and prioritization (six prioritized levels of
interrupts) capability. The interrupt enable register (IER) enables each of the six types of
interrupts and the INT signal in response to an interrupt generation. The IER can also
disable the interrupt system by clearing bits 7:5 and 3:0. When an interrupt is generated,
the IIR indicates that an interrupt is pending and provides the type of interrupt through
IIR[5:0].
Table 6
summarizes the interrupt control functions.

It is important to note that for the framing error, parity error, and break conditions, LSR[7]
generates the interrupt. LSR[7] is set when there is an error anywhere in the RX FIFO,
and is cleared only when there are no more errors remaining in the FIFO. LSR[4:2] always
represent the error status for the received character at the top of the RX FIFO. Reading
the RX FIFO updates LSR[4:2] to the appropriate status for the new character at the top of
the FIFO. If the RX FIFO is empty, then LSR[4:2] are all zeros.
For the Xoff interrupt, if an Xoff 铿俹w character detection caused the interrupt, the interrupt
is cleared by an Xon 铿俹w character detection. If a special character detection caused the
interrupt, the interrupt is cleared by a read of the IIR.
