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 enables selecting items of interest
that will logically flow up to the masterStatus flag.

terStatus byte and its associated programmable alerts are configured using th
d as described in Chapter 10. Programming Guidelines.
Table 93 below shows the definition of the bit mask for configuring the status signals.

Configuration Fields Field ID Valid Values Description
hardwareStatusEnable 0x0010 Any Bit mask of enabled hardware status signals

sensorStatusEnable 0x0013 Any Bit mask of enabled sensor status signals
hardwareStatusEnable Field
This field is a bit mask of the hardwareStatus field (refer to BIT Status Fields on page 98). This field allows the user
to determine which low level hardwareStatus field signals will flag the hardwareStatus and masterStatus flags in the
BITstatus field. Any asserted bits in this field imply that the corresponding hardwareStatus field signal, if asserted,
will cause the hardwareStatus and masterStatus flags to be asserted in the BITstatus field.
