Timer Interface Module (TIM)
10.2 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 10-1 is a block diagram of the TIM.
10.3 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 with 7-frequency internal bus clock
prescaler selection
• Free-running or modulo up-count operation
• Toggle any channel pin on overflow
• TIM counter stop and reset bits
10.4 Pin Name Conventions
The TIM share two I/O pins with two port D I/O pins. The full name of the
TIM I/O pins are listed in Table 10-1. The generic pin name appear in the
text that follows.
