Hello Sir, i want to ask how to add 390ns or 0.39us for dead time ?

My systemclock = 64 MHz

My AHB Prescaler = 4

so my HCLK = 16 MHz

and because of APB1 Prescaler = 1

then my APB1 peripheral clocks = 16 MHz

So, what number i should put in the dead time configuration ?

Thanks a lot !

Problem solved.

Deadtime = the value that you want (in my case 390ns) * systemcoreclock

(Keep in mind that systemcoreclock is HCLK, not systemclock)

So my deadtime would be = 390ns * 16 MHz = 6.24 = 6 or 7
