Internode test results are reflected here. (The bits all turn back OFF when the
internode test is started.)
Bits 0 to 5 turn ON when their applicable error occurs.
The error code for the error that occurred is stored in bits 13 to 15. The meanings
of the error codes are shown in the following table.

Internode tests are executed repeatedly as long as the Internode Test Start
Switch, one of the Unit Control Switches in the CIO area, remains ON.
In this word, specify in hexadecimal the number of times that the internode test is
actually to be executed.
0000 to FFFF (Hex): 0 to 65,535 times
When the count reaches FFFF (Hex), it will start over again at 0. The count value
will be retained until the internode test is restarted.
Note When a routing table error or a transmission parameter error occurs, the number
of internode tests is not incremented.
