 204
 205           When only that slow-clock is available, some peripherals lose
 206           functionality.  Many can't issue wakeup events unless faster
 207           clocks are available.  Some lose their operating state and
 208           need to be completely re-initialized.

 217           On AT91rm9200 chips where you're using a system clock derived
 218           from the 32768 Hz hardware clock, this tick rate should divide
 219           it exactly: use a power-of-two value, such as 128 or 256, to
 220           reduce timing errors caused by rounding.
 221
 222           On AT91sam926x chips, or otherwise when using a higher precision
 223           system clock (of at least several MHz), rounding is less of a
 224           problem so it can be safer to use a decimal values like 100.
