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

442 help
443 On AT91rm9200 chips where you're using a system clock derived
444 from the 32768 Hz hardware clock, this tick rate should divide
445 it exactly: use a power-of-two value, such as 128 or 256, to
446 reduce timing errors caused by rounding.
447
448 On AT91sam926x chips, or otherwise when using a higher precision
449 system clock (of at least several MHz), rounding is less of a
450 problem so it can be safer to use a decimal values like 100.
