comStatus Field
9.13
The comStatus field contains flags that indicate various external communication
conditions and alerts that are not errors or problems (See Table 52). The comStatus flag
in the BITstatus field is the bit-wise OR of the logical AND of the comStatus field and
the comStatusEnable field. The comStatusEnable field is a bit mask that allows the user
to select items of interest that will logically flow up to the masterStatus flag.

softwareStatus Field
9.14
The softwareStatus field contains flags that indicate various software conditions and
alerts that are not errors or problems (See Table 53). 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.

The sensorStatus field contains flags that indicate various internal sensor conditions and
alerts that are not errors or problems (See Table 54). 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 the Master Status
9.16
The masterStatus byte and its associated programmable alerts are configured using the
Read Field and Write Field command as described in Section 8, Advanced Commands.
Table 55 shows the definition of the bit mask for configuring the status signals.
