Introduction
Introduction
The example demonstrates the the configuration of user space registers for various features in the PMIC. The application configures the thermal monitoring, voltage monitoring, GPIO pin, Timer and gets the status. Set/Get/clear IRQ mask and flag Use Pmic_io(Rx/Tx)Byte Api to direct access of register. Refer the PMIC datasheet for more information on the parameters configured. The example passes if the configuration and get status is success.
