ALS Data Registers
In order to update ALS Data Registers ALS_STATUS
must be read first. The ALS channel data is stored
in two 8-bit registers and shall be interpreted as
16-bit data across 2 registers. All ALS data samples
stored are generated in the same integration cycle.
Reading these bytes consecutively (low byte
before high byte) ensures that the data is
concurrent. The data, stored in the ALS_DATA
registers, is obtained from a 26-bit wide result
buffer depending on settings of ALS_SCALE in
MEAS_MODE0 and ALS_MSB_POSITION in MEAS_
MODE1. The ALS_STATUS register indicates
whether the ALS data is scaled or unscaled. In case
ALS_MSB_POSITION is exceeded, data is 0xFFFE. In
case of analog saturation, data is 0xFFFF.
