# ARM Defines and Linker Options

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