hardwareStatusEnable Field
This field is a bit mask of the hardwareStatus field (refer to
on page ). 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.
comStatusEnable Field
This field is a bit mask of the comStatus field(refer to
on page ). This field allows the user to
determine which low level comStatus field signals will flag the comStatus and masterStatus flags in the BITstatus
field. Any asserted bits in this field imply that the corresponding comStatus field signal, if asserted, will cause the
comStatus and masterStatus flags to be asserted in the BITstatus field.
softwareStatusEnable Field
This field is a bit mask of the softwareStatus field (refer to
on page ). This field allows the user to
determine which low level softwareStatus field signals will flag the softwareStatus and masterStatus flags in the
BITstatus field. Any asserted bits in this field imply that the corresponding softwareStatus field signal, if asserted,
will cause the softwareStatus and masterStatus flags to be asserted in the BITstatus field.
sensorStatusEnable Field
This field is a bit mask of the sensorStatus field (refer to
on page ). This field allows the user to
determine which low level sensorStatus field signals will flag the sensorStatus and masterStatus flags in the
BITstatus field. Any asserted bits in this field imply that the corresponding sensorStatus field signal, if asserted, will
cause the sensorStatus and masterStatus flags to be asserted in the BITstatus field.
