Read access gates off changes to the register; the register is reenabled only when reset via EOI. Any successive
interrupts which occur at DCHI, IET2, IET1, ISCI, IEOC, ISD, IUSD und IUSA during the read-out phase and
before a reset with EOI are trapped by an interrupt pipeline. If this happens, the message at NINT resp. D1/SOC
or D2/SOB cannot be deletet by EOI, i.e. NINT resp. D1/SOC or D2/SOB constantly remains on low. In this
instance, EOI fills the overcurrent message from the pipeline.
