Clock configuration

#define CLOCK_EXT_OSC   (12000000UL)
 
#define CLOCK_PLL_MUL   (83)
 
#define CLOCK_PLL_DIV   (12)
 
#define CLOCK_FWS   (4) /* 4 is save for 84MHz */
 

Enable external oscillator for driving the slow clock

Warning
Many (older?) arduino-due boards do not have the external 32khz oscillator soldered on, so only enable this after you make sure its equipped on your specific board
