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
Generation
• Programmable TIM Clock Input
– Seven-Frequency Internal Bus Clock Prescaler Selection
– External TIM Clock Input (4-MHz Maximum Frequency)
• Free-Running or Modulo Up-Count Operation
• Toggle Any Channel Pin on Overflow
• TIM Counter Stop and Reset Bits
• Modular Architecture Expandable to Eight Channels
