Configuration Register
The configuration register allows the user to program
various DS7505 options such as conversion resolution,
thermostat fault tolerance, thermostat polarity, thermo-
stat operating mode, and shutdown mode. The configu-
ration register is arranged as shown in Figure 5 and
detailed descriptions of each bit are provided in Table
2. The user has read/write access to all bits in the con-
figuration register except the MSB (NVB bit), which is a
read-only bit. All bits in the register but the NVB bit are
NV EEPROM backed by shadow SRAM, and thus
power-up in their programmed state. Once written to
the shadow SRAM, values can be stored in EEPROM
by issuance of a Copy Data command from the master
(see the Command Set section for more details). If the
values are not copied to the EEPROM, the device pow-
ers up with the factory default settings or the last values
that were copied to the EEPROM. The NVB bit is SRAM
and powers up in the state shown in Table 2.

BIT NAME
FUNCTIONAL DESCRIPTION
NVB
NV Memory Status
Power-up state = 0, read only
NVB = 1Write to an NV memory cell is in progress.
NVB = 0NV memory is not busy.
R1
Conversion Resolution Bit 1
Factory power-up state = 0
Sets conversion resolution (see Table 3).
R0
Conversion Resolution Bit 0
Factory power-up state = 0
Sets conversion resolution (see Table 3).
F1
Thermostat Fault Tolerance Bit 1
Factory power-up state = 0
Sets the thermostat fault tolerance (see Table 4).
F0
Thermostat Fault Tolerance Bit 0
Factory power-up state = 0
Sets the thermostat fault tolerance (see Table 4).
POL
Thermostat Output (O.S.) Polarity
Factory power-up state = 0
POL = 0O.S. is active low.
POL = 1O.S. is active high.
TM
Thermostat Operating Mode
Factory power-up state = 0
TM = 0Comparator mode.
TM = 1Interrupt mode.
See the OperationThermostat section for a detailed description of these modes.
SD
Shutdown
Factory power-up state = 0
SD = 0Active conversion and thermostat operation.
SD = 1Shutdown mode.
See the Shutdown Mode section for a detailed description of this mode.
