Inspect quarterly trends of HWWD bits for indication of negative function

Famis 27546 Inspect quarterly trends of HWWD bits for indication of negative function.

I believe I'm just looking for channels that have no bit switching (motion) on them, which would indicate that the HWWD is no longer working properly.

First image is how the trends display on the ndscope, it's a bit hard to see all of the channels here.
But in the second image I just scaled the channels by enough to see that there is motion on all 4 channels.
ETMX HWWD apparently has the least amount of HWWD bit switching action, but there are bits being switched.
But ETMY has been a bit busy switching bits!
