 201           On AT91rm9200 chips where you're using a system clock derived
 202           from the 32768 Hz hardware clock, this tick rate should divide
 203           it exactly: use a power-of-two value, such as 128 or 256, to
 204           reduce timing errors caused by rounding.
 205
 206           On AT91sam926x chips, or otherwise when using a higher precision
 207           system clock (of at least several MHz), rounding is less of a
 208           problem so it can be safer to use a decimal values like 100.
