hardwareStatus Field
The hardwareStatus field contains flags that indicate various internal hardware conditions and alerts that are not
errors or problems. The hardwareStatus flag in the BITstatus field is the bit‐wise OR of the logical AND of the
hardwareStatus field and the hardwareStatusEnable field. The hardwareStatusEnable field is a bit mask that allows
the user to select items of interest that will logically flow up to the masterStatus flag.
