Unleash efficiency and performance with step-down/step-up regulator based on MIC23099 and PIC32MZ2048EFH100

/*!
 * \file 
 * \brief MIC23099 Click example
 * 
 * # Description
 * MIC23099 click represent single AA/AAA cell step-down/step-up regulator 
 * with battery monitoring.
 *
 * The demo application is composed of two sections :
 * 
 * ## Application Init 
 * Application Init performs Logger and Click initialization.
 * 
 * ## Application Task  
 * This example demonstrates the use of MIC23099 Click board by checking 
 * the state of power good pin and sends note via UART Terminal 
 * if the state is low.
