Catastrophic Trip Indicator (CTI): A 1 indicates that the internal thermal
sensor temperature is above the catastrophic setting.
sensor temperature is above the catastrophic setting.

RO
0b
Hot Trip Indicator (HTI): A 1 indicates that the internal thermal sensor
temperature is above the Hot setting.
temperature is above the Hot setting.
5
RO
0b
Aux0 Trip Indicator (A0TI): A 1 indicates that the internal thermal sensor
temperature is above the Aux0 setting.
temperature is above the Aux0 setting.
4
RO
0b
Thermometer Mode Output Valid (TOV): A 1 indicates the Thermometer
mode is able to converge to a temperature and that the TR register is reporting a
reasonable estimate of the thermal sensor temperature. A 0 indicates the
Thermometer mode is off, or that temperature is out of range, or that the TR
register is being looked at before a temperature conversion has had time to
complete.
