Select this if you want Suspend-to-RAM to save the most power
possible (without powering off the CPU) by disabling the PLLs
and main oscillator so that only the 32 KiHz clock is available.
When only that slow-clock is available, some peripherals lose
functionality. Many can't issue wakeup events unless faster
clocks are available. Some lose their operating state and
need to be completely re-initialized.

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.
