Description
The clock tick is not very precise on at91rm9200. The attached patch improves the situation by:
- Not reloading the "period interval timer" register in the interrupt handler since this is done automaticaly.
- Use integer rounding in the calculation of the "period interval timer" register value to get as close as posible to the CONFIGURE_MICROSECONDS_PER_TICK value.
Please apply
Thanks
