Table 5. CONFIGURATION REGISTER BIT DESCRIPTIONS
BIT NAME
(USER ACCESS)
DONE—Temperature
Conversion Done
(Read Only)
DONE = 1. Temperature conversion is complete.
Power-up state = 0.
THF = 0. The measured temperature has not exceeded the value
stored in the T
H
register since power-up.
THF = 1. At some point since power-up the measured temperature
has been higher than the value stored in the T
H
register. THF remains
a 1 until it is overwritten with a 0 by the user, the power is cycled, or
a Software POR command is issued.
Power-up state = 0.
TLF = 0. The measured temperature has not been lower than the
value stored in the T
L
register since power-up.
TLF = 1. At some point since power-up the measured temperature
has been lower than the value stored in the T
L
register. TLF remains a
1 until it is overwritten with a 0 by the user, the power is cycled, or a
Software POR command is issued.
Power-up state = 0.
NVB = 1. A write to EEPROM
memory is in progress.
NVB = 0. NV memory is not busy.
R1—Resolution Bit 1
(Read/Write)
Sets conversion, T
H
, and T
L
resolution (see Table 6).
R0—Resolution Bit 0
(Read/Write)
Sets conversion, T
H
, and T
L
resolution (see Table 6).
Power-up state = last value written to this bit.
POL = 1. T
OUT
is active high.
POL = 0. T
OUT
is active low.
Power-up state = last value written to this bit.
1SHOT = 1. One-Shot Mode. The Start Convert T command initiates
a single temperature conversion and then the device goes into a low-
power standby state.
1SHOT = 0. Continuous Conversion Mode. The Start Convert T
command initiates continuous temperature conversions.
*Stored in EEPROM
FUNCTIONAL DESCRIPTION
