Timer Interface Module (TIM)
8.1 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.
a block diagram of the TIM.
This particular MCU has two timer interface modules which are denoted as TIM1 and TIM2.
8.2 Features
Features of the TIM include:
8.3 Pin Name Conventions
The text that follows describes both timers, TIM1 and TIM2. The TIM input/output (I/O) pin names are
T[1,2]CH0 (timer channel 0) and T[1,2]CH1 (timer channel 1), where “1” is used to indicate TIM1 and “2”
is used to indicate TIM2. The two TIMs share four I/O pins with four I/O port pins. The external clock input
for TIM2 is shared with the an ADC channel pin. The full names of the TIM I/O pins are listed in
The generic pin names appear in the text that follows.

Two input capture/output compare channels:
–
–
Buffered and unbuffered pulse-width-modulation (PWM) signal generation
Programmable TIM clock input

Free-running or modulo up-count operation
Toggle any channel pin on overflow
TIM counter stop and reset bits
Rising-edge, falling-edge, or any-edge input capture trigger
Set, clear, or toggle output compare action
7-frequency internal bus clock prescaler selection
External clock input on timer 2 (bus frequency ÷2 maximum)
References to either timer 1 or timer 2 may be made in the following text by
omitting the timer number. For example, TCH0 may refer generically to
T1CH0 and T2CH0, and TCH1 may refer to T1CH1 and T2CH1.
