The start application command is used to quit the bootloader and start the application
loaded.
The start application is performed by a watchdog reset.
The best way to start the application from a user defined entry point is to configure the
FCB (Fuse Configuration Byte) before launching the watchdog. Then, depending on the
configuration of the BRV2:0 field, the hardware boots from the selected memory area.
