|
Proximity sensor cancellation pulse duration in half clock cycles.
|
||
|
|
This parameter determines a cancellation pulse duration.
|
||
|
|
The cancellation is applied in the integration phase to cancel out
|
||
|
|
unwanted reflected light from very near objects such as tempered glass
|
||
|
|
in front of the sensor.

|
|
Proximity sensor crosstalk cancellation current in picoampere.
|
||
|
|
This parameter adjusts the current in steps of 2400 pA up to 276000 pA.
|
||
|
|
The provided value must be a multiple of 2400 and in one of these ranges
|
||
|
|
[60000 - 96000]
|
||
|
|
[120000 - 156000]

|
[180000 - 216000]
|
||
|
|
[240000 - 276000]

|
This parameter is used in conjunction with the cancellation duration.
