53:C:/electrotic/WinAVR/bin/../lib/gcc/avr/3.4.3/../../../../avr/include/avr/delay.h **** implemented as count-down loops with a well-known CPU cycle

58:C:/electrotic/WinAVR/bin/../lib/gcc/avr/3.4.3/../../../../avr/include/avr/delay.h **** In general, for long delays, the use of hardware timers is
59:C:/electrotic/WinAVR/bin/../lib/gcc/avr/3.4.3/../../../../avr/include/avr/delay.h **** much preferrable, as they free the CPU, and allow for

61:C:/electrotic/WinAVR/bin/../lib/gcc/avr/3.4.3/../../../../avr/include/avr/delay.h **** running. However, in particular for very short delays, the
62:C:/electrotic/WinAVR/bin/../lib/gcc/avr/3.4.3/../../../../avr/include/avr/delay.h **** overhead of setting up a hardware timer is too much compared
