Datasheet

B/D/F/Type:

0/0/0/MCHBAR

Address Offset: CDAh

Default Value:

00h

Access:

RO 

Size:

8 bits

This read only register provides trip point and other status of the thermal sensor.

All bits in this register are reset to their defaults by MPWROK.

7

RO

0b

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

6

RO

0b

Hot Trip Indicator (HTI): A 1 indicates that the internal thermal sensor 
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.

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.

RO

0b

Direct Catastrophic Comparator Read (DCCR): This bit reads the output of 
the Catastrophic comparator directly, without latching via the Thermometer 
mode circuit. Used for testing.

0

RO

0b

Direct Hot Comparator Read (DHCR): This bit reads the output of the Hot 
comparator directly, without latching via the Thermometer mode circuit. Used 
for testing.
