3.11.9 COMP_DATA

Address

16HEX and 17HEX and 18HEX

Default value

00HEX and 00HEX and 00HEX

Bit

16HEX

COMP_DATA_0[7:0]

17HEX

COMP_DATA_1[15:8]

18HEX

COMP_DATA_2[19:16]

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

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.
