#49 SDR Sensor Capabilities Parse & Display
The current "sdr get" command displays the "Event Message Control" but not the other fields in the Sensor Capabilities byte.
Especially, when Sensor Threshold Access Support is not matching the Readable/Settable Masks, it is more important to display this Access Control setting along with the masks setting rather than only displaying the masks setting. Note, the capabilities byte takes the precedence.
The mismatch configuration includes:
1. Threshold Access Support = 00b (no thresholds) or 11b (fixed unreadable)
vs. any non-zero Settable/Readable Threshold Mask
2. Threshold Access Support = 01b (readable (i.e. not settable) vs. any non-zero Settable Threshold Mask
3. Threshold Access Support = 01b (readable) or 10b (readable & settable) vs. zero Settable/Readable Threshold Mask accordingly. This is a problem because the Settable/Readable Threshold Mask is settable via the Set Sensor Thresholds Command. Although the SDR indicates no thresholds enabled by the mask, as long as the capabilities byte allows, these thresholds may be enabled at a later time.
Hello,
please, can you post some examples of mismatched output?
Thanks.

The SDR Record is:

In this SDR record, the Sensor Capabilities is D5h. That is, Sensor Threshold Access Support is 01b, thresholds are readable (not settable). Therefore, Settable Thresholds should be empty above.
