8.2.3.4 Status Register
The Status Register can be used to read IP timeout, error and interrupt status.
The IP timeout time is app. 8µs.
An IP timeout occurs if the IP module fails to generate the IP ACK# signal within the IP timeout
time. An IP timeout is not reported to the PCI9030 or the PCI Master, but in the Status Register.
For timeout reads all F's are returned.
