Configuration Register

The Configuration register controls the functionality of

the temperature measurements.

bit 7

bit 0

Legend:

R = Readable bit

W = Writable bit

U = Unimplemented bit, read as ‘0’

-n = Value at POR

‘1’ = Bit is set

‘0’ = Bit is cleared

x = Bit is unknown

bit 7

MASK1: Masks the ALERT/THERM2 signal (Note 1).

1

=ALERT is disabled; any out-of-limit condition will not assert the signaled pin

0

=ALERT is enabled; any out-of-limit condition will assert the signaled pin (default)

bit 6

RUN/STOP: Initiates ADC conversions

1

= Standby mode, thus reducing supply current significantly, though the SMBus will still be active

(Note 2)

0

= Active mode (continuously running); the ADC will convert temperatures in a continuous mode

(default)

bit 5

ALERT/THERM2: sets the ALERT/THERM2 pin to act as either an SMBALERT# signal or as the

THERM2 signal.

1

= the ALERT/THERM2 pin acts as the THERM2 signal and Bit 7 is ignored

0

= the ALERT/THERM2 pin acts as the ALERT (SMBALERT#) signal (default)

bit 3-0

Reserved: Unimplemented bit, read as ‘0’.

Note 1:

This bit is ignored if the ALERT/THERM2 pin is configured as THERM2 signal by Bit 5.

2:

If this bit is high and the One-shot register is written to, the ADC will execute a temperature measurement

and then return to Standby mode.
