 233           When only that slow-clock is available, some peripherals lose
 234           functionality.  Many can't issue wakeup events unless faster

 245           On AT91rm9200 chips where you're using a system clock derived
 246           from the 32768 Hz hardware clock, this tick rate should divide
 247           it exactly: use a power-of-two value, such as 128 or 256, to
 248           reduce timing errors caused by rounding.
 249
 250           On AT91sam926x chips, or otherwise when using a higher precision
 251           system clock (of at least several MHz), rounding is less of a
 252           problem so it can be safer to use a decimal values like 100.
