ENABLE Register

Preset each applicable registers and its bits as per required

operation before activating PON. After PON is set, it is required

to wait 100μs settling time and then enable PEN. In order to

modify register configurations during operation, it is required

to set PEN=PON=0 firstly to avoid any unexpected behavior or

corrupted proximity results. Disabling PON resets the device

state machine, but all the register values will retain. After the

configuration change done, set the PON bit and wait 100μs

settling time, and then enable PEN to re-activate the

corresponding functionalities.
