## Clock Frequency and Timer Calculations
The clock frequency determines the speed of all operations in a microcontroller.
### Formulas
**Clock Period = 1 / Frequency**
**MIPS = Clock Frequency / Cycles per Instruction**
**Timer Frequency = Clock / Prescaler**
Prescalers divide the clock to create slower timer ticks, useful for generating precise time intervals without consuming CPU cycles.

Exemple Résolu
16 MHz clock, 1 CPI (ARM Cortex-M), prescaler of 64.
- Clock period: 1 / 16e6 = 62.5 ns
- MIPS: 16e6 / 1 = 16 MIPS
- Timer frequency: 16e6 / 64 = 250,000 Hz
- Timer tick: 64 / 16e6 = 4.000 microseconds
