Ambient light intensity count value can be obtained by reading registers of this device.
Ambient light intensity count is a 15-bit wide number plus a valid bit and hence word (two
bytes) read operation is needed, as shown in Figure 16. After receiving the two byte data, the
I²C master terminates this transaction by issuing a NACK command to indicate that the master
only wanted to read two bytes from the device. The master generates a stop condition to end
this transaction.
