4.4
The SBC Sleep Mode has the advantage of reducing the current consumption to a
minimum. During this mode the integrated voltage regulator for external supply is turned
off. In case the connected microcontroller needs to get activated periodically, the Cyclic
Wake feature in combination with the SBC Sleep Mode can be activated (see
