UVB_DATA_2[19:16]

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

Register data is already temperature compensated. 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.
