3.11.2 Trimming parameter readout
The trimming parameters are programmed into the devices’ non-volatile memory (NVM) during
production and cannot be altered by the customer. Each compensation word is a 16-bit signed or
unsigned integer value stored in two’s complement. As the memory is organized into 8-bit words,
two words must always be combined in order to represent the compensation word. The 8-bit
registers are named calib00…calib25 and are stored at memory addresses 0x88…0xA1. The
corresponding compensation words are named dig_T# for temperature compensation related
values and dig_P# for pressure compensation related values. The mapping is shown in Table 17.

3.11.3 Compensation formula
Please note that it is strongly advised to use the API available from Bosch Sensortec to perform
readout and compensation. If this is not wanted, the code below can be applied at the user’s risk.
Both pressure and temperature values are expected to be received in 20 bit format, positive,
stored in a 32 bit signed integer.
7 Use only recommended for high-level programming languages like Matlab™ or LabVIEW™
8 Use only recommended for 8-bit micro controllers
