softwareBIT Field
The softwareBIT field contains flags that indicate various types of software errors. Each type has an associated
message with low level error signals. The softwareError flag in the BITstatus field is the bit‐wise OR of the
softwareBIT field.

softwareAlgorithmBIT Field
The softwareAlgorithmBIT field contains flags that indicate low level software algorithm errors. The algorithmError
flag in the softwareBIT field is the bit‐wise OR of the softwareAlgorithmBIT field.
