Decimal Fraction Temperature Data Format (Local and Remote Temperature Low Figure 13 shows the internal register structure of the Bytes) TMP421/22. The 8-bit Pointer Register is used to TEMPERATURE REGISTER LOW BYTE VALUE address a given data register. The Pointer Register (0.0625 °C RESOLUTION)(1) TEMP identifies which of the data registers should respond ( °C) STANDARD AND EXTENDED BINARY HEX to a read or write command on the Two-Wire bus. 0 0000 0000 00 This register is set with every write command. A write 0.0625 0001 0000 10 command must be issued to set the proper value in 0.1250 0010 0000 20 the Pointer Register before executing a read 0.1875 0011 0000 30 command. Table 3 describes the pointer address of 0.2500 0100 0000 40 the TMP421/22 registers. The power-on reset (POR) 0.3125 0101 0000 50 value of the Pointer Register is 00h (0000 0000b). 0.3750 0110 0000 60 0.4375 0111 0000 70 0.5000 1000 0000 80 0.5625 1001 0000 90 0.6250 1010 0000 A0 0.6875 1011 0000 B0 0.7500 1100 0000 C0 0.8125 1101 0000 D0 0.8750 1110 0000 E0 0.9385 1111 0000 F0 (1) Resolution is 0.0625 °C/count. All possible values are shown. The TMP421/22 contain multiple registers for holding Figure 13.
