493 | Select this if you want Suspend-to-RAM to save the most power | |

508 | help | |
509 | On AT91rm9200 chips where you're using a system clock derived | |
510 | from the 32768 Hz hardware clock, this tick rate should divide | |
511 | it exactly: use a power-of-two value, such as 128 or 256, to | |
512 | reduce timing errors caused by rounding. | |
513 | ||
514 | On AT91sam926x chips, or otherwise when using a higher precision | |
515 | system clock (of at least several MHz), rounding is less of a | |
516 | problem so it can be safer to use a decimal values like 100. | |
