Hello,

I'm new in microcontroller world and have a question. What is preload register in TIM3? I really don't understand it's meaning. So could somebody help me, please.

Preload defines whether a value is latch immediately into the working/used register, or if it is latched at the UPDATE event. ie when the TIM rolls over. This permits a defined transition rather than one occurring randomly within the period of the timer. Say I wanted to control the duty from one period to the next.
