Delay functions and "__builtin_avr_delay_cycles".

2011-07-04 by Cat C

Hi there,
Looking at the delay functions, I see that:	void _delay_us 
          (
          double 
           __us )has a maximal possible delay is 768 us / F_CPU in MHz.
But:If the avr-gcc toolchain has __builtin_avr_delay_cycles(unsigned long) 
support, maximal possible delay is 4294967.295 us/ F_CPU in MHz.
How do I know if the avr-gcc toolchain has __builtin_avr_delay_cycles(unsigned long) support?
Thanks,
Cat
