| 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. |
