Overall Test Results
Using commands that retrieve test results
No command is available that allows you to directly retrieve the overall
test results that combine the test results for all channels.
Using the status register
The condition register and event register under the questionable status
event register each provides bit 10, from which you can obtain the overall
test result (0: Pass, 1: Fail).
