TABLE 1. REGISTER SET
ISL76683
0: disable ADC-core
Number of clock cycles; n-bit resolution
Read-Only data register that contains the least significant byte of the timer
Read-Only data register that contains the most significant byte of the timer
1: enable ADC-core
0: Normal operation
1: Power-down Mode
0: Integration is internally timed
1: Integration is externally sync/controlled by I
Selects ADC work mode
0: Diode1’s current to unsigned 16-bit data
1: Diode2’s current to unsigned 16-bit data
2: Difference between diodes (I1 - I2) to signed 15-bit data
3: reserved

Always set to logic 0. Factory use only.
Always set to logic 0
0: Interrupt is cleared or not yet triggered
1: Interrupt is triggered
Always set to logic 0. Factory use only.
Selects the gain so range is
0: 0 to 1000 lux
