Description
ALS Integration Time. Sets the internal integration time of ALS/Color analog to digital
converters in increments of 2.78ms. The power on reset value is 0xFF. The ADC
maximum count (or saturation) value depends on the integration time. It is the lesser
of either:
65535 (16-bit saturation) or
The result of equation: Count_MAX = 1024 X CYCLES
