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 a single timer interface modules which are denoted as TIM1.
8.2 Features
Features of the TIM include:
8.3 Pin Name Conventions
The text that follows describes the timer, TIM1. The TIM input/output (I/O) pin names are T1CH01 (timer
channel 01). The TIMER shares three I/O pins with three port C I/O port pins. The timer clock input is used
by TIM1 modules. The full names of the TIM I/O pins are listed in
