18.2 Features
Features of the TIM include:
18.3 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 port D I/O port pins.
18.4 Functional Description

that can operate as a free-running counter or a modulo up-counter. The TIM counter provides the timing
reference for the input capture and output compare functions. The TIM counter modulo registers,
TMODH:TMODL, control the modulo value of the TIM counter. Software can read the TIM counter value
at any time without affecting the counting sequence.
The two TIM channels (per timer) are programmable independently as input capture or output compare
channels. If a channel is configured as input capture, then an internal pullup device may be enabled for
that channel. See

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
Rising-edge, falling-edge, or any-edge input capture trigger
Set, clear, or toggle output compare action

summarizes the timer registers.
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.
References to either timer 1 or timer 2 may be made in the following text by
omitting the timer number. For example, TSC may generically refer to both
T1SC and T2SC.
