This status register, displayed in
signals. The DEU status register is read only. Writing to this location results in address error being reflected
in the DEU interrupt status register.

Error interrupt: This status bit reflects the state of the error interrupt signal, as sampled by
the controller interrupt status register
0 DEU is not signaling error
1 DEU is signaling error
Done interrupt: This status bit reflects the state of the done interrupt signal, as sampled by
the controller interrupt status register
0 DEU is not signaling done
1 DEU is signaling done
Reset done. This status bit, when high, indicates that DEU has completed its reset
sequence, as reflected in the signal sampled by the appropriate channel.
0 Reset in progress
