7.6.3 Configuration Register
The Configuration Register is an eight-bit read/write register used to store bits that control the operational modes
of the temperature sensor. Read/write operations are performed MSB first. The format and power-up and reset
value of the Configuration Register is shown in Table 7. All registers are updated at the end of the data byte.

7.6.4 Temperature Limit Registers
The THIGH and TLOW registers are used to store the temperature limit thresholds for the TMP103 watchdog
function. At the end of each temperature measurement, the TMP103 compares the temperature results to each
of these limits. If the temperature result is greater than the THIGH limit, then the FH bit in the configuration register
is set to 1. If the temperature result is less than the TLOW limit, then the FL bit in the configuration register is set
to 1; see Figure 12.
Table 8 and Table 9 describe the format for the THIGH and TLOW registers. Power-up reset values for THIGH and
TLOW are: THIGH = 60°C and TLOW = –10°C. The format of the data for THIGH and TLOW is the same as for the
Temperature Register.
