 165           Select this if you want Suspend-to-RAM to save the most power
 166           possible (without powering off the CPU) by disabling the PLLs
 167           and main oscillator so that only the 32 KiHz clock is available.
 168
 169           When only that slow-clock is available, some peripherals lose
 170           functionality.  Many can't issue wakeup events unless faster
 171           clocks are available.  Some lose their operating state and
 172           need to be completely re-initialized.

 181           On AT91rm9200 chips where you're using a system clock derived
 182           from the 32768 Hz hardware clock, this tick rate should divide
 183           it exactly: use a power-of-two value, such as 128 or 256, to
 184           reduce timing errors caused by rounding.
 185
 186           On AT91sam926x chips, or otherwise when using a higher precision
 187           system clock (of at least several MHz), rounding is less of a
 188           problem so it can be safer to use a decimal values like 100.
