Always set to 0.
PS_ADC_REC[2:0]
Increases the irLED pulse width and ADC integration time by a factor of
(2 ^ PS_ADC_GAIN) for all PS measurements.
Care must be taken when using this feature. At an extreme case, each of the
three PS measurements can be configured to drive three separate irLEDs,
each of which, are configured for 359 mA. The internal sequencer does not
protect the device from such an error. To prevent permanent damage to the
device, do not enter any value greater than 5 without consulting with Silicon
Labs.
For Example:
0x0: ADC Clock is divided by 1
0x4: ADC Clock is divided by 16
0x5: ADC Clock is divided by 32
