 * @brief eFuse3 Click example
 *
 * # Description
 * This library contains API for the eFuse 3 Click driver.
 * The library contains drivers to enable/disable the device, 
 * for reading ADC voltage, overflow status, output and current value [ A ].
 *
 * The demo application is composed of two sections :
 *
 * ## Application Init
 * Initializes SPI driver and set default configuration.
 *
 * ## Application Task
 * This is an example that demonstrates the use of the eFuse 3 Click board. 
 * Read and display device status information and current value [ A ].
 * The eFuse 3 includes an overvoltage clamp the circuit that limits the output voltage
 * during transients but does not shut the unit down, 
 * thereby allowing the load circuit to continue its operation.
 * The Electronic Fuse is to limit current and current limit 
 * Current limit ( 0.1 A - 1.8 A ) depends on the choice of resistor wired 
 * on the Rlimit ( 1 Ohm - 15 Ohm ) connector.
 * For example, for Rlimit resistance of 1 Ohm, current limit is 1 A 
 * ( 3.5 Ohm - 0.5 A, 7 Ohm - 0.25 A ). 
 * Read details from the ON Semiconductor NIS6150 datasheets.   
 * Results are being sent to the Usart Terminal where you can track their changes.
