help
On AT91rm9200 chips where you're using a system clock derived
from the 32768 Hz hardware clock, this tick rate should divide
it exactly: use a power-of-two value, such as 128 or 256, to
reduce timing errors caused by rounding.
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.
