7.5 Interrupts
The SC16IS752/SC16IS762 has interrupt generation and prioritization (seven prioritized
levels of interrupts) capability. The interrupt enable registers (IER and IOIntEna) enable
each of the seven types of interrupts and the IRQ signal in response to an interrupt
generation. 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, Line
Status Register bit 7 (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 flow character detection caused the interrupt, the interrupt
is cleared by an Xon flow character detection. If a special character detection caused the
interrupt, the interrupt is cleared by a read of the IIR.
