8.9 Interrupt Identification Register (IIR)
The IIR is a read-only 8-bit register which provides the source of the interrupt in a
prioritized manner.
Table 20
shows Interrupt Identification Register bit settings.
[1]
Modem interrupt status must be read via MSR register and GPIO interrupt status must be read via IOState
register.
[2]
Only available on SC16IS750/SC16IS760.
