Bit description

prox_on_ovs

R/W

This register controls the proximity oversampling

function of the higher proximity threshold. In its

default configuration the oversampling is

disabled. If the register value is greater than zero

the numeric value of the register defines the

number of proximity measurements the ADC

reading must be above/below the PROX_THH

interrupt. Please refer to chapter 7.7 and

Figure 31 which illustrates the proximity

oversampling function with its related control

registers and a dedicated timing diagram.

0: Oversampling disabled

1: Single oversampling

2: Double oversampling

3: Tripple oversampling

…

7: 7 times oversampling

2:0

prox_off_ovs

This register controls the proximity oversampling

function of the lower proximity threshold. In its

default configuration the oversampling is

disabled. If the register value is greater than zero

the numeric value of the register defines the

number of proximity measurements the ADC

reading must be below/above the PROX_THL

interrupt. Please refer to chapter 7.7 and

Figure 31 which illustrates the proximity

oversampling function with its related control

registers and a dedicated timing diagram.
