CONFIGURATION REGISTER
The configuration register allows the user to customize the DS1626/DS1726 conversion and thermostat
options. It also provides information to the user about conversion status, EEPROM activity, and
thermostat activity. The configuration register is arranged as shown in Figure 6 and detailed descriptions
of each bit are provided in Table 3. This register can be accessed using the Read Config and Write Config
commands. Note that the R1, R0, CPU, and 1SHOT bits are stored in EEPROM and all other
configuration register bits are SRAM.

BIT NAME
(USER ACCESS)
FUNCTIONAL DESCRIPTION
DONE
(Read Only)
Power-up state = 1.
DONE = 0. Temperature conversion is in progress.
DONE = 1. Temperature conversion is complete.
THF
(Read/Write)
Power-up state = 0.
THF = 1. The measured temperature has reached or exceeded the value stored in the
T
H
register. THF will remain a 1 until it is overwritten with a 0 by the user, the
power is cycled, or a Software POR command is issued.
TLF
(Read/Write)
Power-up state = 0.
TLF = 1. The measured temperature has equaled or dropped below the value stored
in the T
L
register. TLF will remain a 1 until it is overwritten with a 0 by the user, the
power is cycled, or a Software POR command is issued.
NVB
(Read Only)
Power-up state = 0.
NVB = 1. Write to an E
2
memory cell is in progress.
NVB = 0. NV memory is not busy.
R1*
(Read/Write)
Power-up state = last value written to this bit.
Sets conversion resolution (see Table 4).
Initial state from factory = 1.
R0*
(Read/Write)
Power-up state = last value written to this bit.
Sets conversion resolution (see Table 4).
Initial state from factory = 1.
CPU*
(Read/Write)
Power-up state = last value written to this bit.
CPU = 1. Stand-alone mode is disabled.
CPU = 0. Stand-alone mode is enabled when RST = 0. See CPU BIT AND STAND-
ALONE THERMOSTAT OPERATION section for more information.
Initial state from factory = 0.
1SHOT*
(Read/Write)
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.
Initial state from factory = 0.
