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

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

Configuring masterStatus
The masterStatus byte and its associated programmable alerts are configured using the Read Field and Write Field
command as described in
The Table below shows the definition of the bit mask
for configuring the status signals.
