Hello Jim,

exactly what I wrote. To get a frequency of 60/4 you need to toggle
TWICE in 4 clocks. If you tell me that a 16 MHz AVR can generate more
than 8 MHz output that would really be news to me because that would
be 2 instructions in one cycle, a superscalar AVR8. 

Please no offense, I think it was only a misunderstanding in wording. 
And still the ARM needs 2 cycles to toggle a pin while the AVR does it
in one, it's just a fact that the ARM can almost run four cycles
before the AVR is done with one. 

The only reason I am comparing this to the AVR because the older
devices which needed 8 cycles to toggle a pin were actually slower in
toggeling than a 16 MHz AVR and that has been a major complaint in
this forum back then.
