"DELETE"s the interrupt message (change-of-input message;
interrupt status register, overcurrent message)
accepts successive interrupts from the pipeline, deletes the
messages at NINT resp. D1/SOC or D2/SOB when the pipeline is empty.
Bit automatically resets to ’0’.

Bypass overcurrent filter
(r)
Filters for the overcurrent message are active
(r)
Bypass for the filters: overcurrent messages are reprocessed in their unfiltered state.
