Well, there are situations where you have to delay for just a single cycle (e.g. if you're setting a port output, and want to read back an input that depends from it). Sure, it's possible to use __delay_cycles(1) but most people probably find it more "natural" to just insert a single NOP there. Maybe we could add something like <avr/cpufunc.h> or such. -- cheers, J"org .-.-. --... ...-- -.. .
