Here is a “light” C-code of a clock switching function using automatic clock monitoring.
C Code Example
void ClockSwiching (unsigned char clk
#define CLOCK
#define CLOCK
#define CLOCK
#define CLOCK
#define WD
#define WD
unsigned char previous
}
}
// Disable interrupts
// Save the current system clock source
// Enable the new clock source
// Wait for clock validity
// Switch clock source
// Wait for effective switching
// Shut down unneeded clock source
// Re-enable interrupts
// Enable the watchdog in automatic reload mode
temp = SREG; asm ("cli");
