TSL2771 − Register Set

ADC Channel Data Registers (0x14 - 0x17)

ALS data is stored as two 16-bit values. To ensure the data is

read correctly, a two-byte read I²C transaction should be used

with auto increment protocol bits set in the command register.

With this operation, when the lower byte register is read, the

upper eight bits are stored in a shadow register, which is read

by a subsequent read to the upper byte. The upper register will

read the correct value even if additional ADC integration cycles

end between the reading of the lower and upper registers.

Proximity Data Registers (0x18 - 0x19)

Proximity data is stored as a 16-bit value. To ensure the data is

read correctly, a two-byte read I²C transaction should be

utilized with auto increment protocol bits set in the command

read, the upper eight bits are stored into a shadow register,

which is read by a subsequent read to the upper byte. The upper

ends between the reading of the lower and upper registers.
