Peripheral Real Time ClockEdit
DescriptionEdit
The Real Time Clock interface available on AXEL Lite is based on NXP MMPF0100 PMIC.
The Real Time Clock is kept operative through the AXEL Lite PMIC_LICELL pin (J2.14): the LICELL pin provides for a connection of a coin cell backup battery or a “super” capacitor.
A small capacitor should be placed from LICELL to ground under all circumstances.
For more information about PMIC RTC functionality, please refer to the MMPF0100 datasheet.
Pin mappingEdit
The Pin mapping is described in the Pinout table section
