Table_4._Continuous_Mode_Register
Note: Continuous mode is independent of the manual configuration mode setting.
In automatic mode (MANUAL = 0), reading the contents of TIM[2:0] and CDR bits reflects the automatically generated
values from an internal timing register and are read-only. In manual mode (MANUAL = 1), the contents of TIM[2:0] and
CDR bits can be modified by the users through the I
The CDR bit controls the current division ratio. The photodiode current is divided as shown in Table 6.

Low-Power Digital Ambient Light Sensor
Default mode of configuration is used for the IC. In this mode, CDR, TIM[2:0] bits are automatically
determined by the internal autoranging circuitry of the IC.
Manual mode of configuration is used for the IC. In this mode, CDR, and TIM[2:0] bits can be programmed by
the user.
Default mode. The IC measures lux intensity only once every 800ms regardless of integration time. This mode
allows the part to operate at its lowest possible supply current.
Continuous mode. The IC continuously measures lux intensity. That is, as soon as one reading is finished, a
new one begins. If integration time is 6.25ms, readings are taken every 6.25ms. If integration time is 800ms,
readings are taken every 800ms. In this mode, the part consumes slightly higher power than in the default
mode.
Current not divided. All of the photodiode current goes to the ADC.
Current divided by 8. Only 1/8 of the photodiode current goes to the ADC. This mode is used in
high-brightness situations.
