  	help
  	  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.
