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 5. 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.
