UV_COMP_DATA_2[19:16]

UVBS compensation (UV_COMP) channel digital output data (unsigned integer, 13 to 20 bit, LSB aligned).

Register carries UVBS temperature compensation data. See Table 3.3 for details.

When an I²C read operation is active and points to an address in the range 07HEX to 18HEX, all registers in this range are

locked until the I²C read operation is completed or this address range is left.

This guarantees that the data in the registers belongs to the same measurement cycle. New measurement data is stored into

temporary registers and the actual *_DATA registers are updated as soon as there is no on-going I²C read operation to the

address range 07HEX to 18HEX.
