- On AT91rm9200 chips where you're using a system clock derived

- it exactly: use a power-of-two value, such as 128 or 256, to

- On AT91sam926x chips, or otherwise when using a higher precision
- system clock (of at least several MHz), rounding is less of a
- problem so it can be safer to use a decimal values like 100.
