| 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 | |

| 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. | |
