Function Description
Auto Scale Control of ASL/IR mode
Auto Scale
0 ASL/IR_IT and ASL/IR-Gain are controlled by register 0x02[6:4] and 0x02[3:2].

Control
When ASC is active, ASL/IR_IT and ASL/IR-G are automatically scaled by internal circuit; the
(ASC mode)
1 _{ASL/IR_IT and ALS/IR_G can only be read as the internal scaled ones, and ALS/IR Data and Hi/Lo}
threshold would be defined as 16 bits of [15:0].

0x04
ALS/IR Data Low Byte [7:0]
ALS/IR Data High Byte [11:8],
ASC mode = [15:8]
Read ALS/IR_Data 12 bits of [11:0].
If ASC mode is active, the data is auto scaled as 16 bits of [15:0].
0x05
0x06
ALS/IR_HiTH Low Byte [7:0]
ALS/IR_HiTH High Byte [11:8],
ASC mode = [15:8]
The ALS/IR High Threshold registers provide the values to be used as the high trigger
point for interrupt generation. An interrupt is generated when the value of ALS/IR
conversion is greater than the high threshold. If ASC mode is active, the data is defined
as 16 bits of [15:0].
0x07
0x08
ALS/IR_LoTH Low Byte [7:0]
ALS/IR_LoTH High Byte [11:8],
ASC mode = [15:8]
The ALS/IR Low Threshold registers provide the values to be used as the low trigger
point for interrupt generation. An interrupt is generated when the value of ALS/IR
conversion is lower than the low threshold. If ASC mode is active, the data is defined as
16 bits of [15:0].
