This document explains how to achieve 32-bit timer resolution using the link system in STM32F10x microcontrollers. It provides the principles and timer configurations for achieving 32-bit input capture timer resolution.
The document describes a method to chain two 16-bit timers within STM32F10x microcontrollers to obtain 32-bit resolution. This configuration is necessary for measuring external signal periods of several hundreds of seconds or generating delays with large periods that exceed the native range of a single timer.
It is achieved by chaining two 16-bit timers together using the specific configuration of the timer link system.
The two basic operating modes are input capture mode and output compare mode.
