Timer overflow time calculation formula

Tout = ((ARR + 1)*(PSC + 1)) / Tclk
|
||
Given Tclk as 84MHz, we need Tout to be 200ms or 200000us. Let's assume PSC is 839, substituting it into the formula gives ARR = 19999.
|
||
With these calculated values, both ARR and PSC are within the range of 0 to 65535, so we can use this parameter set.
