DIE_TEMP (0x0F)
The register contains the die temperature in °C expressed as an 8-bit 2's complement number. The sensitivity of the temperature
sensor is factory trimmed to 1°C/LSB. The temperature sensor offset is not factory trimmed and must be calibrated by the user
software if higher absolute accuracy is required. Note: The register allows for temperature measurements from -128°C to 127°C
but the output range is limited to -40°C to 125°C. The temperature data is updated on every measurement cycle.

Table 31. CTRL_REG1 Description
DR[2:0]
Output data rate selection. Default value: 000.
See
for more information.
OS [1:0]
This register configures the over sampling ratio for the measurement. The selected number of samples is collected and
averaged before being placed in the output data registers. The oversampling setting made here applies to both the triggered
and active modes of operation.
Default value: 00.
See
for more information.
FR
Fast Read selection. Default value: 0.
0: The full 16-bit values are read.
1: Fast Read, 8-bit values read from the MSB registers (Auto-increment skips over the LSB register in burst-read mode).
TM
Trigger immediate measurement. Default value: 0
0: Normal operation based on AC condition.
1: Trigger measurement.
If part is in ACTIVE mode, any measurement in progress will continue with the highest ODR possible for the selected OSR.
In STANDBY mode triggered measurement will occur immediately and part will return to STANDBY mode as soon as the
measurement is complete.
AC
Operating mode selection. Note: see
for details. Default value: 0.
0: STANDBY mode.
1: ACTIVE mode.
ACTIVE mode will make periodic measurements based on values programmed in the Data Rate (DR) and Over Sampling
Ratio bits (OS).
