84 #| Normally the first thing your program should do is set the clock prescaler,
85 #| so your program will run at the correct speed. You should also set this
86 #| variable to same clock speed. The _delay_ms() macro uses this, and many
87 #| examples use this variable to calculate timings. Do not add a "UL" here.
