4 / 17 page DS1848 4 of 17 Memory Location Name of Location Function of Location 00h to 47h (the Table Select Byte, E0h, must be set to 01h or 02h to access the Look- Up Tables) 00h to 7Fh (the Table Select Byte, E0h, must be set to 00h to access the User EEPROM Memory) User Defined Look-Up Table (LUT) User Memory This block contains the user-defined temperature settings of the resistors. Values between 00h and FFh can be written to either table to set the 256 position variable resistors. The first address location, 00h, is used to set the resistor at -40°C. Each successive memory location will contain the resistor setting for the previous temperature +2°C. For example, memory address 01h is the address that will set the resistor in a -38°C environment. For default memory settings and programming the look-up table, refer to the Programming the Look-Up Table (LUT) section of the datasheet. This block is for general-purpose user memory. When shipped from the factory, memory locations 60h – 6Bh contain the same information as found in Look-Up Table 1, memory locations 28h – 33h. Memory locations 6Ch – 77h contain the same information as found in Look-Up Table 2, memory locations 28h – 33h. E0h Table Select Byte Writing to this byte determines if one of the two 72x8 EEPROM look-up tables or the user EEPROM memory is selected for reading or writing. 00h (User EEPROM selected) 01h (Look-Up Table 1 selected) 02h (Look-Up Table 2 selected) E1h Configuration Byte TAU – Temperature/Address Update TEN – Temperature Update Enable AEN – Address Update Enable Default setting is 03h, TAU = 1, TEN = 1 and AEN = 1. TAU becomes a 1 after a temperature and address update has occurred as a result of a temperature conversion. The user can write this bit to 0 and check for a transition from 0 to 1 in order to verify that a conversion has occurred. If TEN = 0, the temperature conversion feature is disabled. The user sets the resistor in “manual mode” by writing to addresses F0h and F1h to control resistors 0 and 1, respectively. TAU TEN AEN |
