timer_timeout.h

/*******************************************************************************
 * Timer Timeout library for MSP43x V01 - timer_timeout.h
 *
 * - Use a timer and interrupt to tick a 32bit unsigned variable
 * - period selected by user, between 1us and 1ms
 * - enable to use timer interruption with less then 1MHz, very useful for
 *   small microcontrollers (tested at 100us - 10kHz)
 *
 * Author: Haroldo Luiz Moretti do Amaral - agaelema@gmail.com
 * https://www.embarcados.com.br/author/agaelema/
 * https://www.github.com/agaelema
 *
 * Based on idea presented by: Felipe de Andrade Neves Lavratti
 * - generic delay and timeout library
 * https://www.embarcados.com.br/biblioteca-de-timer-delay-timeout/
 *
 ********************************************************************************
 * Changes:
 * - Separate setup of timer in different file ("timer_timeout_setup")
 * - remove unused code
 *
 * v0.3 - 2017/08/10
