 * @brief USB-C Sink 3 Click example
 *
 * # Description
 * This example demonstrates the use of USB-C Sink 3 Click board™ 
 * by setting DC power requests and control for Type-C connector-equipped devices (TCD).
 *
 * The demo application is composed of two sections :
 *
 * ## Application Init
 * Initializes SPI, I2C and ADC modules and log UART.
 * After driver initialization the app set default settings:
 * Voltage Selection: 5 [V] and Power: 15.0 [W].
 *
 * ## Application Task
 * In this example, the app configures Power Data Objects (PDO) 
 * highest priority profile and requests power from a standard USB PD source adapter.
 * It interprets power input requirements (voltage/current and maximum power) from the TCD.
 * The example uses two configurations: 
 *  - Voltage 5 [V] and Power 15.0 [W]
 *  - Voltage 9 [V] and Power 18.0 [W]
 * Results are being sent to the Usart Terminal where you can track their changes.
 *
 * @note
 * FAULT LED flickering notified of the system status:
 *  - Charging: Breathing light (2 sec dimming), 1 cycle is 4 sec.
 *  - Fully charged: Continuously lit Charging current < 500mA.
 *  - Mismatch: 1s flicker Voltage or power mismatch. Non-PD power source, 1 cycle is 2sec.
 *  - Fault: 300ms flicker OVP, 1 cycle is 600ms.
