Timer Interface Module (TIM1 and TIM2)
17.1 Introduction
This section describes the timer interface (TIM) module. The timer on this part consists of a 2-channel
and a 1-channel timer that provides a timing reference with input capture, output compare, and
pulse-width-modulation functions.
This particular MCU has two timer interface modules which are denoted as TIM1 and TIM2.
