SMD  I²C Digital Ambient Light Sensor
ALS-PDIC17-57B/TR8
Device Command
There are three command codes are provided for I²C master to control the ambient light sensor. The specific
function corresponding to each command code is elaborate in Table 2.

1xxx_xxxx
(binary code)
0x04
0x08
0x30
Function
Shut-down mode, this is the default state after applying V_DD power to the device.
During shut-down mode, users can do the communication test. Except the MSB
must be logic 1, the value written to the command register will not change any
function and can be read back via the I²C bus by issuing Receive Byte Protocol.
Activate the ambient light sensor. The integration time is controlled by I²C
commands, start and stop integration.
Start integration: This command will reset the ADC register to 0x0000 and begin a
new integration.
Stop integration: This command will stop the integration and set the valid bit (D[15])
high.
