Proximity detection uses an Automatic Pulse Control (APC) mechanism that adjusts the number of pulses per measurement based on the magnitude of the reflected IR signal. As the magnitude of the signal increases, the number of pulses decreases. Proximity detection uses a 10-bit ADC that is extended to a 14-bit dynamic range for PDATA using the following formula: PDATA = ADCvalue x (16 / proximity pulses) PDATA is the average response of the non-masked proximity photodiodes. If one or more photodiodes are masked (CFG2 register 0x9F), the proximity response will remain the same since it is an average of the active photodiodes. PDATA is therefore proportional to the reflected energy per pulse, independent of the number of pulses used.
