190         help
191           Select this if you want Suspend-to-RAM to save the most power
192           possible (without powering off the CPU) by disabling the PLLs
193           and main oscillator so that only the 32 KiHz clock is available.
194 
195           When only that slow-clock is available, some peripherals lose
196           functionality.  Many can't issue wakeup events unless faster
197           clocks are available.  Some lose their operating state and
198           need to be completely re-initialized.

206        help
207           On AT91rm9200 chips where you're using a system clock derived
208           from the 32768 Hz hardware clock, this tick rate should divide
209           it exactly: use a power-of-two value, such as 128 or 256, to
210           reduce timing errors caused by rounding.
211 
212           On AT91sam926x chips, or otherwise when using a higher precision
213           system clock (of at least several MHz), rounding is less of a
214           problem so it can be safer to use a decimal values like 100.
