 * # Description
 * This application collects data from the sensor, calculates it and then logs
 * the result.
 *
 * The demo application is composed of two sections :
 * 
 * ## Application Init 
 * Initializes driver and performs the device configuration which puts Time Slot A
 * in enabled mode and LEDX2 (IR diode) to active state.  Before the device configuration, the
 * SW reset will be performed and in this way we will put the registers in initial state.
 * 
 * ## Application Task  
 * Logs PD1-PD4 data on USB UART
