Forum Post: Value counter Timer

Hello,

I use example dmTimerCounter and I see in comment 700ms between two interrupt.

I don't see prescaler in program.

I see:

#define TIMER_INITIAL_COUNT (0xFF000000u)
#define TIMER_RLD_COUNT (0xFF000000u)

Can you explain me how to calculate 700ms with 0xFF000000 and generaly how to calculate interrupt time with count load value.

Thanks
