1) these addresses allow write access, too
• D_OUT, H_CAL, T_CAL, H_ADC, T_ADC: These registers correspond to the signal
• STATUS: This register contains internal status information as well as the chip version
• EEPROM: These registers contains the EEPROM based parameter-set of the device
• TEST: This register activates several test modes necessary for accessing internals of
Note: To access the registers (except STATUS, H_ADC, T_ADC, D_OUT and TEST)

4.2.1
This register contains a 16bit signed value. When read as unsigned value and this value
is larger than 32767, it is necessary to subtract 65536 to get a signed value again:

the internal digital signal processor must be deactivated as it has priority over
interface read and write commands. Please check out the TEST register content
how to disable the DSP.
