Master BIT and Status (BITstatus) Field
9.2
The BITstatus field is the global indication of health and status of the DMU380SA Series
product (See Table 29). The LSB contains BIT information and the MSB contains status
information.
There are four intermediate signals that are used to determine when masterFail and the
hardware BIT signal are asserted. These signals are controlled by various systems checks
in software that are classified into three categories: hardware, communication, and
software. Instantaneous soft failures in each of these four categories will trigger these
intermediate signals, but will not trigger the masterFail until the persistency conditions
are met.
There are four intermediate signals that are used to determine when the masterStatus flag
is asserted: hardwareStatus, sensorStatus, comStatus, and softwareStatus. masterStatus is
the logical OR of these intermediate signals. Each of these intermediate signals has a
separate field with individual indication flags. Each of these indication flags can be
enabled or disabled by the user. Any enabled indication flag will trigger the associated
intermediate signal and masterStatus flag.
