softwareAlgorithmBIT Field
9.10
The softwareAlgorithmBIT field contains flags that indicate low level software algorithm
errors (See Table 49). The algorithmError flag in the softwareBIT field is the bit-wise OR
of this softwareAlgorithmBIT field.

The softwareDataBIT field contains flags that indicate low level software data errors (See
Table 50). The dataError flag in the softwareBIT field is the bit-wise OR of this
softwareDataBIT field.

hardwareStatus Field
9.12
The hardwareStatus field contains flags that indicate various internal hardware conditions
and alerts that are not errors or problems (See Table 51). 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.
