PS_RATE is an 8-bit compressed value representing a 16-bit multiplier. This multiplier,
in conjunction with the MEAS_RATE time, represents how often PS Measurements are
made.
Example Values:
0x00: Autonomous PS Measurements are not made
0x08: PS Measurements made every time the device wakes up
(0x0001 x timeValueOf(MEAS_RATE))
0x32: PS Measurements made every 10 times the device wakes up
(0x000A x timeValueOf(MEAS_RATE)
0x69: PS Measurements made every 100 times the device wakes up
(0x0064 x timeValueOf(MEAS_RATE)
ALS_LOW_TH is an 8-bit compressed value representing a 16-bit threshold value.
The uncompressed value represented by ALS_LOW_TH (when used in conjunction
with uncompressed value represented by ALS_HI_TH) forms a window region
applied to ALS_VIS or ALS_IR measurements for interrupting the host.
