Internode Test
168
Note 1. The contents of the test status area and test runs/errors area are maintained
until the internode test is run again.
2. When the number of tests counts to the maximum value (FFFF), subse-
quent internode test runs are counted from 0. However, the maximum value
is maintained and further errors are not counted when the number of errors
reaches the maximum value.
