3.1.1 Battery Status
To determine the battery voltage of XDK, the battery is connected via a management circuit to pin
PD7 of the MCU. This pin can be configured with the ADC software module to allow sampling the
battery voltage. Note that the values measured are not the actual battery voltage, since this is too
high for the MCU in to be connected directly. A voltage divider is used to bring down the voltage to
~50% of the current voltage supplied to the system via the power management circuit.
The battery charger of XDK gives information about the current charging mode via the green LED
of XDK. However, this pin is not connected to the MCU. Determining the current charging mode in
the software running on XDK is therefore not possible. The green LED only shows the charging
status and cannot be controlled by software.

3.1.2 Sleep Management
XDK SDK currently does not support putting the MCU of XDK to sleep. While there is a software
module called RTC, this module is neither used on XDK SDK nor has it been tested on XDK.
Therefore, using it is at your own risk and may potentially be very frustrating.
