After updating the error status registers and flags, copy the “regular” NT8 channel configuration words into the NT8
I/O image. Begin 7-second timer to wait for the NT8 to change its I/O image back to the regular channel configuration.
Again, the time required by the NT8 I/O image is dependent on the NT8 configuration.
