Timer Interface Module (TIM1 and TIM2)
18.1 Introduction
This section describes the timer interface (TIM) module. The TIM is a two-channel timer that provides a
timing reference with input capture, output compare, and pulse-width-modulation functions. Figure 18-1
is a block diagram of the TIM.
This particular MCU has two timer interface modules which are denoted as TIM1 and TIM2.
