 237
 238           When only that slow-clock is available, some peripherals lose
 239           functionality.  Many can't issue wakeup events unless faster
 240           clocks are available.  Some lose their operating state and

 250           On AT91rm9200 chips where you're using a system clock derived
 251           from the 32768 Hz hardware clock, this tick rate should divide
 252           it exactly: use a power-of-two value, such as 128 or 256, to
 253           reduce timing errors caused by rounding.
 254
 255           On AT91sam926x chips, or otherwise when using a higher precision
 256           system clock (of at least several MHz), rounding is less of a
 257           problem so it can be safer to use a decimal values like 100.
