4.2. Dynamic change of the configuration pins

If the configuration pins shall dynamically be changed in the application, the setup and hold time as shown in the diagram below have to be

used for a safe operation of the IC.

4.3. Charge pump on/off through DATA_RDY strap pin

The DATA_RDY pin is used as a strap pin to enable/disable the charge pump. At power-up, the voltage level on DATA_RDY is checked.

In case of a logic-low level, which is set by the internal pull-down resistor, the charge pump is on by default. In case of a logic-high level,

which can be set by an external 10k pull-up resistor, the charge pump is off by default (see figure below).
