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.

|
|
|
|
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.
