16.2.5 TEMP_IN (Address 0x13)
This 2-byte register allows the host system to write ambient temperature data to ENS160 for
compensation. The register can be written at any time. TEMP_IN_LSB should be written first
as the update is recognized on a write to TEMP_IN_MSB.

TEMP_IN Integer Part (Kelvin)
TEMP_IN Fractions
The ENS160 required input format is: temperature in Kelvin * 64
(with Kelvin = Celsius + 273.15).
Example: For 25°C the input value is calculated as follows: (25 + 273.15) * 64 = 0x4A8A.
16.2.6 RH_IN (Address 0x15)
This 2-byte register allows the host system to write relative humidity data to ENS160 for
compensation. The register can be written at any time. RH_IN_LSB should be written first as
the update is recognized on a write to RH_IN_MSB.

The ENS160 required input format is: relative humidity in %rH * 512.
Example: For 50% rH the input value is calculated as follows: 50 * 512 = 0x6400.
