11.2 Introduction
This section describes the timer interface module (TIM2, Version B). The
TIM is a two-channel timer that provides a timing reference with input
capture, output compare, and pulse-width-modulation functions.
Figure
11-1 is a block diagram of the TIM.
11.3 Features
Features of the TIM include the following:
• Two Input Capture/Output Compare Channels
– Rising-Edge, Falling-Edge, or Any-Edge Input Capture Trigger
– Set, Clear, or Toggle Output Compare Action
• Buffered and Unbuffered Pulse Width Modulation (PWM) Signal
