(r)
Output IOx has had an overcurrent state enabled for interupt messages (short circuit)
Read access gates off changes to the register; the register is reenabled only when reset via EOI. Any successive
interrupts which occur 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.
The SCIx bits may be erased selectable by reenabeling IENx after disable.
’0’ is output for IOx pins in input mode. SCIx reports for IOx.

These signals act as error analysis and does not generate any interrupts (real time, no register). ’0’ is output for
IOx pins in input mode. SCx reports for IOx.
